Depending on the application need, detector arrays can be selected with single or two-stage TEC cooling, deep cooled to -55°C or water cooled down to -90°C for excellent low light sensitivity. Te latest version of electronics lowers dark noise and improves stray light correction for wider dynamic range over the longer wavelength range.
BaySpec provides its Spec2020 software with any order at no additional charge. A full software development kit (SDK) with dll is available to support new applications development efforts. A variety of fibre optic accessories, from regular fibre bundles and probes to specialised high temperature probes, to broadband light sources can be selected for turn-key sampling. Applications include process control, food safety, pharmaceutical, astronomy, agriculture, remote monitoring, material science, biomedical, particle measurements, light source characterisation and other industrial uses.
In other news, Enhanced Spectrometry has announced that its RamMics M532 Raman microscopes now can be turned into highly efficient and cost- effective 2D scanning systems for Raman mapping. A motorised stage with a 0.36 µm step allows resolution of 2–3 µm particles,
one shot with spectral range from -1000 to -7 cm-1 (anti-Stokes component).
Finally, according to McPherson, enhanced ultraviolet response and good light throughput with a robust, open architecture set its Commander system apart.
Tis triple spectrometer for Raman works in the 185- 2200 nm region with a selection of diffraction gratings. Operating at f/5 it has impressive light gathering power. It delivers edge rejection within 5cm-1 in the visible spectral region. Te instrument is free from chromatic aberrations as it uses mirrors throughout.
which allows multiple research opportunities within a single Raman system.
Also, in September the company launched its new handheld RaPort analyser, a novel device for chemical analysis in the fields of forensics, security and pharmaceuticals. RaPort is designed to bring a laboratory quality tool to a handheld class of
analytical devices.
Te company says its solutions make the analysis of low wavenumber Raman bands (in the region below 140 cm-1) easy and affordable. Meanwhile innovative Raman filters ensure spectral range from 7 up to 4000 cm-1 with spectral resolution 3 cm-1 (Stokes component) simultaneously in
Bio Rad releases latest spectroscopy software B
io Rad Laboratories, a multinational manufacturer and distributor of life science research and clinical diagnostic products,
has released KnowItAll Informatics System 2013 spectroscopy software. The software offers comprehensive solutions
for spectral analysis, identification, search, data management, and reporting. It supports multiple instrument vendor file formats and techniques including Raman, IR, NIR, NMR, MS and UV-Vis. Combined with one of the world’s largest spectral
reference collections - which contains over 1.4 million spectra - the software helps chemists extract even

greater knowledge from their spectral data. According to the company, the key benefits of
KnowItAll Informatics System 2013 include: additions to ATR-IR, IR, Raman, NMR, and MS reference spectral collections; enhanced Raman spectrum management; performance optimisations and workflow simplifications; advanced GC-MS database building and linking capabilities; and support for multiple spectra of the same technique within a single database record. “We are pleased to introduce this latest edition of
our KnowItAll Informatics System 2013 software and believe our infrared and Raman customers in particular
will be thrilled with the enhancements featured in this new version,” said Gregory M Banik, general manager, Bio Rad Informatics. “KnowItAll 2013, combined with Bio Rad’s comprehensive collection of high-quality spectral reference data, provides our users with enhanced value when performing spectral analysis.” Founded in 1952, Bio Rad is based in Hercules,
California, and serves more than 100,000 research and industry customers through its global network of operations. The company employs approximately 7,300 people
worldwide and had revenues exceeding US$2 billion (€1.5 billion) in 2012.
In addition the aspheric mirrors correct and improve imaging performance for excellent signal levels at the detector, even with weakly emitting samples. Te entrance slit width and intermediate aperture in the filter stage allow users to set slope of the edge rejection as well as the wavelength range at the detector. Te primary spectrograph is vacuum compatible. Te double- monochromator filter stage and sample area may be nitrogen purged to eliminate water and oxygen absorption. Under ideal circumstances, this combination of environmental control allows work to wavelengths as short as 160 nm.
