Palintest launches High Range Manganese Test for Drinking Water

Leading water and chemical analysis company Palintest has developed a new high range test for Manganese in drinking water. The new Manganese HR test now offers a market-leading measurement range of 0.02 to 5 mg/l, without the need for pre-test sample dilution.

The test uses the approved standard Formaldoxime method (ISO 6333), and is supplied in packs containing two sets of tablets. One set of tablets is used to prepare the sample, correcting pH level, and the second tablet reacts with the Manganese. The resultant solution develops an orange/brown colour which indicates the concentration. This test is designed to be used with Palintest’s 7100, 7500 and 8000 model Photometers for precise photometric measurement.

In 2004 the World Health Organisation (WHO) reviewed the health risks posed by Manganese in drinking water, and adopted a new Guideline value of 0.4 mg/l. Concentration levels down to 0.05 mg/l may still cause discolouration of water, leading to consumer dissatisfaction. Similarly, the US EPA recommends a limit of 0.05mg/l because of the staining caused, with some industrial applications requiring levels down to 0.02 mg/l. The new Manganese HR test from Palintest therefore allows a full range of concentration testing from trace to toxic, without extra cost or complexity.

Netherlocks’ interlocks use a linear key transfer system to ensure that processes can only be carried out in the correct order, ensuring each part has been safely completed before the next can be started. Safely completing the previous step in the process sequence will release a unique key that then unlocks the next step; only when a mistake is made will the operator be prevented from proceeding by a key that doesn’t fit or a valve locked in position. This simple principle can be propagated to more complex procedures, but in every case it physically ensures that safety protocols and work orders are followed exactly, leaving no scope for human error.

Projected to produce 800 kt/a of ethylene, 450 kt/a of propylene and 230 kt/a of benzene, the facility consists of an Ethylene Cracker Unit, a Pygas Hydrogenation/Benzene Extraction Unit, a C4 Selective Hydrogenation Unit and various associated utilities. Opened in March 2010, the complex links the nearby SEPL Refinery with downstream chemical units, forming an integrated petrochemical ‘super site’ in Singapore. With plant safety such a critical issue, Netherlocks is proud to offer both its range of high quality, reliable products and many years of experience and expertise in the industrial safety field.

Single fibre assemblies are available with two choices of chemical resistant, non-magnetic sheathing to fit customers’ needs. For general purpose use, Fiberguide’s furcation tubing is comprised of a Kevlar reinforced PVC sleeve over a polypropylene tube. Furcation tubing is non-conductive and protects fibres with a liquid-tight seal.

For more specialized applications, Fiberguide offers stainless steel monocoil sheathing. The monocoil is vacuum compatible and resistant to tight bending, crushing, cutting, kinking and high temperatures.

Both standard cable designs are rated for use at ambient temperatures. Single fibre assemblies are available with core sizes ranging from 50µ to 1000µ and wavelengths from deep UV (DUV) to UV-VIS and VIS-IR. Assemblies are also available upon request with ST and FC connectors, numerical apertures of 0.12 and 0.26, and continuous lengths up to 50 meters.

Ocean Optics Spectrometer Helps Dentists Use Curing Lights More Effectively

New OEM system just what the doctor ordered for Canadian-based BlueLight Analytics Inc

A spectroradiometrically calibrated USB4000 Spectrometer from Ocean Optics (www.oceanoptics.com) is helping dentists to use curing lights more effectively to harden the white resin composites used to fill cavities. The spectrometer is a key component of the Managing Accurate Resin Curing (MARC) system developed by Dr. Richard Price and researchers at Dalhousie University (Halifax, Nova Scotia) and commercialized through BlueLight analytics inc. (www.curingresin.com). Dr. Price has used Ocean Optics equipment in his laboratory since 2002 to measure the output from dental curing lights.  The results of his research have been published in 15 papers internationally.

MARC measures the useful energy a simulated resin restoration receives from a dental curing light, a procedure that is affected by the location of the tooth, the type of resin used, the output of the curing light and the accuracy of the practitioner. Too much or too little exposure of the curing light to the restoration can lessen the lifetime of the filling and potentially damage the tooth.  With the MARC system, which includes a laboratory-grade NIST-referenced USB4000 Spectrometer, dental researchers, educators, manufacturers and clinicians can more accurately measure the irradiance (in mW/cm2) and energy per unit area (in J/cm2) delivered by various curing lights in the hands of different dental professionals.

Slightly larger than a mobile phone, the miniature fibre optic USB4000 Spectrometer uses a 3648-element Toshiba linear CCD array detector and high speed electronics. For the MARC system, the spectrometer has been spectroradiometrically calibrated using Ocean Optics’ NIST-traceable light source (300-1050 nm). MARC also uses the CC3-UV Cosine Corrector to collect radiation over 180º field of view. This collection device helps mitigate the effects of optical interference associated with light collection sampling geometry – for example, the distance of the light to the restoration.

According to Colin Deacon, president and CEO of BlueLight, the potential impact of MARC is great, with 130 million restorations performed each year in the U.S. alone. Selection of the optimum spectrometer manufacturer for the project was critical. “We chose Ocean Optics because of its superior products and customer service,” said Deacon. “We tried some other manufacturers, but there is no question why Ocean Optics is the most widely used and respected manufacturer of miniature spectrometers in the industry.”

In developing MARC, BlueLight worked closely with Ocean Optics’ OEM Engineering Team, which helps OEM customers bring products to market faster and better optimized to commercial requirements. The team offers complete system design capability for OEMs from supply of fibre assemblies and light sources to sensor coatings and sample holders. Ocean Optics is ISO 9001:2008 certified and can support both integrated system and sub-system manufacturing needs.

Omnifit® Labware T-Series Solvent Waste Bottle Cap Traps Harmful Vapours

Integrated test strip gives visual cue to replace trap

To maintain laboratory air quality and safety, Diba has introduced the Omnifit® Labware T-Series Waste Caps.  The chemically inert caps trap and contain escaping vapour generated by HPLC and other lab solvents.  A colour changing indicator strip notifies lab personnel when it is time to replace the vapour trap.

The T-Series waste caps come in a range of bottle thread types and connect to 1/8” OD semi-rigid tubing without requiring additional fittings.  The tubing pushes straight through the cap Luer ports to create a liquid- and vapour-tight seal.  Other tubing sizes can be accommodated using a variety of adapters, without compromising the seal.  A separate ¼”-28 UNF thread port enables connection of a vapour trap and breakthrough indicator unit.

An activated carbon vapour trap isolates any solvent fumes and prevents escape from the system during pressure venting.  When the trap becomes saturated, an integrated indicator strip turns red, alerting staff to replace the trap to prevent unintentional vapour breakthrough.

The unique design also prevents over pressurization. As liquid is collected in the waste bottle, either under pressure or gravity feed, vapour is automatically vented to the trap to prevent explosions or injury.

Castell Safety Interlocks Now Available Much More Quickly

New manufacturing approach has dramatically reduced lead times

Industrial safety specialist Castell (www.castell.com) has adopted an innovative manufacturing process to improve efficiency and benefit end-users, machine builders and distributors alike. The company is the first in the interlocking sector to implement end coding, which allows standard products to be coded at the final, rather than initial, stage of production.

End coding enables the company’s interlocks to be fitted uncoded to machinery and remain there until they are commissioned. The coding scheme can be changed right up until the point that commissioning is accepted, when an authorised coding engineer codes the system. As a result, standard products can now be held as stock with distributors and machine builders, speeding up the supply chain.

The system relies on a coded tablet that is inserted into the lock. Once inserted, the tablet cannot be removed or recoded, which guarantees the integrity and safety of the system. Tablets can be provided within 24 hours of being defined and requested.

Since trapped key interlocks were first designed, the production of any system could not start until each code within the system had been defined. This created a number of potential issues. There was no flexibility during the commissioning phase for alterations once the locks had been fitted. Similarly, since each unit had been individually coded at the start of the manufacturing process, replacement stock required a full set of duplicates to be kept as spares. Machine builders could not stock items and orders could only be placed once end-users had confirmed codes. The product was not readily available as a stock item either at distribution outlets or from the manufacturer. Essentially, each component was a special and as such came with an extended lead time, no matter how frequently that product was used.

Keith Allingham, Castell’s operations director, has welcomed the company’s switch to end coding: “This major innovation will benefit all of our customers and give them the flexibility to ensure their system operates correctly pre-commissioning. This will both speed up commissioning times and deliver maximum system integrity – major advantages for all projects.”
