New Mass Flow Controller from Alicat Performs at High Volumes

Design overcomes limits of high flow rates to maximize speed and accuracy

Alicat Scientific has engineered a new mass flow controller with its highest top flow rate suitable to a wider range of applications. The MCRH can accommodate flow rates of up to 5000 slpm, without compromising speed or precision of gas control. The highly stable controller manages industrial processes with more chaotic upstream fluctuations, such as control of industrial combustion gases, or mass flow into food and packaging processes.

The MCRH 5000 slpm precisely and rapidly controls mass flow rate, volumetric flow rate, or back pressure of gases in high flow processes. To overcome the poor turndown ratio and slow response of existing methods (such as interlinking a meter with an external valve) Alicat designed a new flow geometry. This new design accommodates the higher flow rates, with a low pressure drop of 14.1 psig at full scale. A dual valve design enables a fast 100 millisecond control response time without significantly raising instrument power requirements.

The instrument’s Gas Select firmware includes a library of up to 130 preloaded gases, user selectable in the field. The MCRH 5000 slpm can be programmed with the instrument’s push button menus and onboard display, or via remote connection. Digital communications options include RS-232 or RS-485 serial, Modbus, or PROFIBUS, as well as analog 0-5 Vdc, 1-5 Vdc, and 0-10 Vdc, or 4-20 mA.

Science and Creativity Come Together with Spectroscopy and Pyrotechnics

Ocean Optics’ spectrometer assures special effects colour purity and safety for Le Maitre

Spectrometers from Ocean Optics are being used by Le Maitre Ltd in Surrey to ensure the quality and safety of its close proximity pyrotechnics. Ocean Optics spectrometers measure plasma emission and emissive colour of effects used in theatre productions, concerts, and sporting events. The measurements help Le Maitre ensure these explosive displays are consistently amazing and, most important, safe.

Le Maitre Pyrotechnics Developer Hamish Cavaye, Ph.D., runs live product tests in a silo in rural England. His challenge is to objectively verify that effects are producing the desired colours. As was recently proven with the pop culture “What colour is the dress?” phenomenon, the human eye is easily fooled. Using a spectrometer to verify colour purity, Cavaye looks for particular emission bands indicative of a specific chemical composition.

Measuring the emissive colour of pyrotechnics with a spectrometer also has the ability to signal safety issues. If the spectra identify elements that are not expected, it may indicate contamination. Verifying consistency not only ensures a pleasing colour for the audience but helps assure the safety of patrons and performers.

Measurement speed is also important in testing pyrotechnics, as some effects can last less than a second. With integration times on some Ocean Optics spectrometers as low as 1 ms, Cavaye can easily capture multiple spectra for each effect. Along with needing the precision and accuracy typically required of spectrometer measurements, Le Maitre had the additional challenge of requiring an instrument that was portable and durable. Compact miniature spectrometers can easily be brought to the testing silo and are rugged enough to withstand close proximity to live effects as they are firing.

Ocean Optics recently visited Le Maitre to see its spectrometers and Le Maitre’s effects in action. Watch the explosive video here: http://youtu.be/Nw0bNfNUYuQ?a.

This isn’t the first time Ocean Optics’ spectrometers have felt the heat. They’ve also been used for studying muzzle flashes from rifles, rocket plume emissions, and applications involving flame analysis of metals and other materials.

Ocean Optics Handheld Spectrometer Finalist for Prism Award

Compact IDRaman mini delivers fast, accurate Raman analyses in the field and laboratory

Ocean Optics’ IDRaman mini handheld Raman spectrometer has been selected as a finalist for the Prism Awards for Photonics Innovation. The Prism Awards honour the best new photonics products on the market and draw entries from around the world. The prestigious awards, which are co-sponsored by the trade organisation SPIE and the technology media company Photonics Media, will be awarded at the 2014 Photonics West trade show in February.

Ocean Optics IDRaman mini handheld Raman spectrometer

Ocean Optics IDRaman mini handheld Raman spectrometer

The IDRaman mini is a finalist in the Defense and Security category of the Prism Awards and is distinguished as a small-footprint, high accuracy instrument ideal for applications ranging from first responders identifying explosives to quality control specialists involved in sample authentication.

The IDRaman uses a novel sampling technique called Raster Orbital Scanning (ROS) where a tightly focused laser beam is moved or rastered across the sample in an orbital pattern. This allows an area about 10 times larger than the laser focus spot to be sampled, encountering more Raman active compounds. Because more Raman-active compounds are sampled, the resulting data incorporates a much higher sensitivity without sacrificing resolution. The increased accuracy in the Raman data further provides high confidence when identifying compounds through library matching.

Furthermore, the IDRaman mini is very small, just 9.1 x 7.1 x 3.8 cm (3.6 x 2.80 x 1.5 in.) and weighing about 11 oz. Its small size and operation from two AA batteries makes IDRaman very attractive for applications where a light, portable instrument is desired.

“The powerful performance of the IDRaman mini has captured the attention of both our customers and spectroscopy experts alike,” said Richard Pollard, President of Ocean Optics. “Combining the ROS technology into a truly handheld product makes accurate Raman measurements available for a variety of applications where fast, accurate material identification is important.”

The Prism Awards nomination follows industry recognition earlier in the year when the IDRaman mini claimed the Annual Readers’ Choice Award from Laboratory Equipment magazine.

Ocean Optics Launches STS-UV Microspectrometer

Instrument provides full spectral UV analysis in a tiny footprint

Designed for integration into spectroscopy instrumentation, medical devices, process monitoring and other applications where a small footprint is desired, the STS-UV Microspectrometer from Ocean Optics is a compact yet high-performance spectrometer. Measuring just 40 mm x 42 mm and 24 mm high, this product is optimised for applications in the ultraviolet (190-650 nm) including absorbance measurements, point of care diagnostics, emission spectroscopy and laser characterization. The STS-UV provides powerful performance for full spectral analysis enabling applications where a range of the spectrum is necessary for proper measurements.

Ocean Optics Launches STS-UV Microspectrometer

Ocean Optics Launches STS-UV Microspectrometer

The high signal to noise and wide dynamic range make the STS-UV useful for demanding measurements such as determining the absorbance from dilute solutions. A selection of configurations allows users to optimise optical resolution to a specific application.

Previously released versions of the STS are also available for the visible (350-800 nm) and shortwave near-IR (650-1100 nm) regions of the spectrum. All versions feature the same form factor and comparable performance specifications.

The STS-UV is anchored by a 1024-element detector in a crossed Czerny Turner optical bench. Its optical design and advanced CMOS detector elevate STS to performance levels comparable to larger and more expensive spectrometers. For example, excellent linearity, absorbance repeatability and wavelength accuracy ensure reproducibility even in large production quantities. In addition, high thermal stability performance and low baseline drift ensure that data stays accurate, even under changing environmental conditions.

The STS-UV easily integrates into other devices or can be set up next to a process line for quality control measurements or as part of a lab station. Several software control options, from drivers for LabVIEW and MATLAB to DLLs for direct control of the spectrometer in Java, Linux or Windows, allow users to seamlessly integrate STS. For laboratory experiments, all STS spectrometers are compatible with Ocean Optics’ OceanView spectroscopy software.
