The 1.3-m focal length McPherson Model 209 spectrometer with new micro-step drive can make wavelength steps as small as 0.1 pm.
The new Genova Plus life science UV/vis spectrophotometer is now available from Jenway. With dedicated modes for DNA/RNA analysis, pre-programmed methods for protein analysis plus standard spectrophotometer functions, the user-friendly system is optimised for applications in biochemistry, forensic science, genetics, biotechnology and other life science laboratories. Based on the Jenway 73 series, this new instrument incorporates a large graphical display built into the lid of the unit. Icon-driven software and soft-key navigation ensure fast analysis and ease of use. A large internal memory enables over 300 methods to be stored and, for added convenience, results and methods can be saved to a USB memory stick. In addition to dedicated modes for DNA/RNA analysis, protein assays, nucleic acid purity and optical density, the system can also be used as a standard spectrophotometer with measurement modes for photometrics, concentration, multi-wavelength, spectrum scanning, quantitation and kinetics.
BioDrop, a microvolume cuvette from BioDrop, provides a robust and affordable approach to low volume spectroscopy. Its patent-pending design has the same dimensions as a conventional cuvette but is manufactured in two halves that are held together using two magnets. The precision machining ensures that the path length is accurate and its simple optical layout provides high-energy throughput ensuring accurate measurements over a wide dynamic range and only one path length is required for most experiments. It is easy to use, is robust enough to withstand the knocks and falls commonplace in laboratories and its ergonomic design makes it easy to handle, even with wet gloves. Available in 0.5 mm or 0.125 mm path lengths, it can be used to perform UV/vis spectroscopy on sample volumes as low as 1 µL, making it suitable for life scientists measureming DNA, RNA and protein samples.
High-throughput circular dichroism measurement system which automates CD and UV/vis absorbance measurements for large numbers of samples. A third detector option allows simultaneous fluorescence measurement. The flow system coupled with an ASU-800 autosampler provides precise micro sampling and eliminates complications often associated with automated CD measurements.
CW laser-driven Xenon light source for high power in the 170–2100 nm range. It works by focusing a 1000 nm laser through a Xenon bulb, creating a high-intensity plasma, which gives maximum output over a broad spectral range. For deep-UV operation there is optional purging.
A demountable micro-volume bio cell which uses advanced precision micro-machining techniques and materials to produce a high-energy throughput, ultra-low volume direct sampling solution for life science samples.
UV/vis/NIR microscope based on a double-beam scanning spectrophotometer capable of covering 200–2700 nm. There are three different versions: one for the UV/vis, one with a Peltier-cooled detector for the entire 200–2700 nm range and one with an InGaAs detector for measurements between 200 nm and 1700 nm. All models have a user-selectable slit width for variable resolution, as well as selectable circular apertures and an adjustable rectangular aperture for sample area discrimination.
Compact and easy-to-use spectrophotometer with down to 0.3 µL sample size or standard cuvette. Optimised for analysis of proteins/peptides, and DNA/RNA/oligonucleotides. Has built-in computer.
A full spectrum analyser that performs high-quality process gas analysis measurements simultaneously in the UV and IR. It is able to measure up to eight components using the most favourable absorptions in both UV and IR spectral regions, eliminating cross-sensitivity concerns.
Small-form, double-beam instrument covering the wavelength range of 190–1100 nm. Has an eight-position multi-cell holder and a temperature sensor in the cell compartment, enabling the temperature of the sample to be determined as the analysis is made. The spectrophotometer is controlled by an Android-based tablet with touch screen. A range of accessories is available.
A compact personal UV/vis microvolume spectrophotometer. It is small enough to fit into a drawer but powerful enough to help accelerate life science workflows related to sequencing, PCR/qPCR, protein isolation, antibody production and HLA typing.
Portable spectrometer based on CCD detection with features including spectrum scanning, photometric, quantitative and kinetic methods. Embedded software and touch screen interface allow for ease of use and data storage, which can be transferred to a PC via a USB connection. Viewer software provides data interpretation and reporting functionality. The C30M comes with pre-programmed test methods for the Spectroquant.
With the threat of climate change, understanding the workings of our atmosphere is of crucial importance. Ozone is the most important trace gas in the stratosphere and troposphere and it is monitored by both satellite-borne and ground-based instruments. Accurate knowledge of ozone absorption cross-sections is vital for this work and described in this article.
McPherson's new vacuum spectrometers features stainless steel housings and components for ultra-high vacuum applications. The instruments can achieve 10E-6 T vacuum during operation with elastomer seals and feature master polished optics, multiple entrance and exit port locations and high precision wavelength drives. High reflectivity coatings provide up to 78% reflective efficiency at wavelengths as short as 120 nm and other coatings are available for performance in mid-wave and long-wave infrared applications. An f/4.7 aperture ratio enables good light throughput. Fitted for wavelength scanning and imaging applications, the spectrometers can accommodate many commercial back-thinned, windowless 2D CCD and CMOS sensors and many single channel silicon diode or scintillated photomultiplier-type sensors. The instruments are suitable for experiments involving transient or fast plasma physics, astrophysics, material science or laser-matter interaction experiments. They are available in focal lengths of 0.67 m, 1.0 m, 1.3 m and 2 m and can be prepared for high-vacuum and also ultra-high vacuum applications with all metal seals. Various vacuum compatible accessories are available.
Shimadzu UK has announced a new series of ultra-high performance scanning spectrometers which offer high-precision spectral analysis of a wide range of samples including organic and inorganic compounds, biological samples, optical materials and photovoltaic devices. The small footprint UV-2700 is a double-beam double-monochromator system that covers a wavelength range of 185 nm to 900 nm for direct measurement of high density samples up to 8 Abs. It features an optical system based on the company's Lo-Ray-Ligh diffraction grating, a new holographic grating that gives low stray light and high energy throughput. The UV-2600 model expands the measurement capabilities of the researcher. The instrument's ultra-low stray light grating delivers 5 Abs performance and, by adding the new ISR-2600 Plus dual detector integrating sphere, extends the transmission or reflectance measuring range up to 1400 nm, enabling the user to study UV-vis-NIR transmittance of nanostructures, architectural glass and photovoltaic devices on a more compact bench-top instrument.
Guided Wave has released the ClearView db, a commercially available dual beam photometric process analyser. Incorporating the dual-beam technology from their full spectrum analysers, the company offer an inexpensive, on-line analyser that is simple to operate and easy to maintain while delivery good results. It is suitable for making continuous chemical composition or colour measurements in stable process streams. The simple design can be configured with up to six analytical wavelengths over a wide spectral range of operation (from 400 nm to 2150 nm) and with one or two channels, with no moving optical components. In addition to the general purpose unit, there are two other enclosure options available as well as an optional turbidity port.
