PRODUCT UPDATE
Analysis, test and measurement Estercheck III
Stanhope-Seta, a manufacturer of petroleum test and control instruments, and Pyreos, supplier of thin-film pyroelectric sensors, have launched a handheld bio-diesel analyser. The analyser, called Estercheck III offers a measurement accuracy of 0.2 per cent or below on FAME concentrations in biodiesel up to 60 per cent. The device is optimised for field use to produce early warnings of issues; it has no warm up time, a simple user interface and provides a percentage result in just 60 seconds.
Spectroscopy Fergie
Princeton Instruments has launched the Fergie spectroscopy system, a fully integrated, aberration-free spectrograph with a built-in, low- noise, cooled detector. Featuring a 11 x 7 x 8 inch profile, Fergie provides the high sensitivity and low noise needed to address a wide range of spectroscopy applications.
Its ecosystem of easy-to-use accessories, which includes everything from lasers, fibre optics, and calibration sources to the family of light-coupling Fergie Cubes, allows scientists, educators, and engineers to put together complete experiments in a matter of minutes. For example, a typical Raman experiment that used to take hours to set up can now be ready in less than 90 seconds. Fergie offers spectral resolution (0.13nm/ pixel with a 1,200g/mm grating) that fares very well when compared to the resolution afforded by larger spectrographs with longer focal lengths. Additionally, Fergie’s diffraction-limited imaging (>60lp/mm spatial resolution throughout the focal plane) yields high signal-to-noise ratios and permits multichannel spectroscopy. Every Fergie
CAS 140CT-HR spectroradiometers
Instrument Systems has added new models to its CAS 140CT line of spectroradiometers, which combine the demands of high spectral resolution and short testing times for measurement tasks in production and laboratory environments. The CAS 140CT-HR spectroradiometers
achieve very high spectral resolutions down to 0.2nm for a spectral measuring range of 80nm. Measuring ranges of 120 and 160nm result in spectral resolutions of 0.3 and 0.4nm, respectively.
The spectrograph architecture with its CCD
array allows it to capture the spectrum of the emitter in a single exposure of the detector and thus renders possible integration times down to 10ms. This is especially important for
the measurement of emitters with a pulsed operating mode in the order of milliseconds. The high resolution CAS 140CT-HR is
available in the spectral range from 800 to 1,000nm with 80, 120 and 160nm measuring ranges. Further variations in the VIS spectral range are available on request.

Flame-Chem spectrophotometer systems
Ocean Optics’ new Flame-Chem spectro- photometer systems combine a high performance, compact Flame UV-Vis (200- 850nm) or Vis-NIR (350-1,000nm) spectrometer, with an all-in-one direct-attach light source and cuvette holder, into a single affordable package. Conveniently pre-configured, Flame-CHEM systems are ideal for regular absorbance and transmission measurements in teaching labs and research facilities.
spectrograph has a built-in detector that permits high-sensitivity spectral capture from 190 to 1,100nm. The new spectroscopy system ships with a full-feature version of powerful Fergie software, powered by LightField - Princeton Instruments’ scientific spectroscopy software. Its intuitive GUI helps Fergie users construct experiments in only minutes.

The systems’ direct-attach cuvette holders accept 1cm pathlength cuvettes for measuring absorbance and transmission of liquid samples. The integrated light source is dependent on the system ordered. Flame-Chem UV-Vis systems come with a combined deuterium-tungsten halogen (200-1,100nm) source; a tungsten
Several hundred tests can be performed on a single recharge. The device is designed to register indications
in the field of incorrect fuel mixes for businesses and users who produce, blend, transport and use biodiesel in vehicles and other machines. The Estercheck III uses Pyreos’ Neon technology platform, which uses mid-IR spectroscopy. Neon also has a standardised software interface which allows specialist instrument makers, such as Stanhope-Seta, to load their own analytics, algorithms, user
interfaces and branding onto their customised devices, and to offer online analytics support.
Stanhope-Seta, the launch customer for the platform, used its expertise in test and measurement to add its own analytics to its implementation of the platform.

halogen source with a violet LED (~390- 1,000nm) is supplied with the Flame-Chem Vis-NIR.
While preconfigured with all the accessories
needed, the Flame-Chem systems can easily be customised, providing flexibility as measurement needs change. The light source-cuvette holder can be removed; spectrometer entrance slits can be switched out to adjust the resolution and throughput; and discrete sampling devices can be used in place of the direct-attach accessories.
