Ocean Optics Launches QE Pro Spectrometer

Spectrometer delivers market-best sensitivity and performance

The QE Pro from Ocean Optics is a high-sensitivity, back-thinned CCD array spectrometer with outstanding quantum efficiency, wide dynamic range and extremely low noise operation for applications with low light levels and where wide concentration ranges are measured.

The QE Pro’s optical design maximises performance for a range of application needs. With its 18-bit A/D, QE Pro has dynamic range performance that makes it the highest sensitivity miniature spectrometer available today. This is significant for users monitoring emission spectroscopy, especially fluorescence and Raman, where signals may be weak and minimum detectable sample limits are often challenging. In addition, for both absorption and reflectance in quality control applications, QE Pro provides lower limits of detection and enables measurements over a wider concentration range.
QEProRelease

For kinetics researchers and scientists requiring fast, full spectrum acquisitions, the QE Pro provides onboard buffering capability. The 15,000 spectra onboard buffer maintains data integrity by buffering time-stamped spectra for USB communications. Buffering enables full-spectrum kinetics measurements, such as those used in chemical and enzyme kinetics or protein folding to be performed every 8 milliseconds — or 125 measurements per second.
Thermoelectric control of the detector improves the stability of the detector for lengthy measurements, where thermal noise convolutes the signal. TEC cooling dramatically reduces thermal noise and holds The QE Pro’s stability to 4 dark counts over a 60°C ambient temperature range. This stability allows the spectrometer to be used for demanding online and at-line quality control measurements and environments susceptible to temperature changes.
QE Pro spectrometers are also available with replaceable, precision laser-cut slit and aperture assemblies for SMA 905 and FC connectors. Replaceable slits give users more freedom in spectrometer design and the ability to switch among applications such as fluorescence and absorbance as easily as replacing a few screws. The slits are available with SMA 905 or FC connectors and are available separately or as part of a kit comprising one each of 5 µm, 10 µm, 25 µm, 50 µm, 100 µm and 200 µm width slits and one SMA bulkhead with no slit installed.

EasiDrive – the most versatile valve operation tool available

Smith Flow Control’s EasiDrive portable valve actuator is quite possibly the most versatile valve operation tool available. Carried in a rucksack, it is specially designed for use with valves requiring a large number of turns or which are otherwise difficult to operate because of high torque or harsh climate conditions.

EasiDriveSystems

With the EasiDrive the operator has absolute control when opening and closing different sized valves with varying torque requirements. One person can efficiently drive multiple valves with a single tool, reducing fatigue and risk of injury and resulting in major cost and time savings. It can be used in virtually any industry, from oil refineries and petrochemical plants to power stations and paper mills.

Key features of the EasiDrive:
• Low cost alternative to permanent actuators
• No permanent power supply required
• Ideal for minimum facilities installations
• Suitable for all climatic conditions
• Wide band torque capability with variable torque adjustment as standard
• Ideal for moving tight or partially-seized valves
• Adaptable to any size/type of valve
• Eliminates operator fatigue and greatly reduces the risk of injury
• No ‘kickback’ often associated with other torque devices
• Variable output torque – so no damage to valves by ‘over-torquing’
• Reduces work crew tasks to one-man operation
• Fully portable – can manage banks of valves with a single drive tool

The ‘reaction kit’, which prevents a torque kickback, is especially useful as valve movement is always fully controlled, preventing operator injury and fatigue. In addition, the variable torque output feature, which prevents excessive torque being applied, ensures proper and safe valve operation at all times.

EasiDrive is highly versatile and can be powered by air, electricity or battery, giving the user ultimate control over their preferred choice. It can also be custom designed to suit specific site requirements.
