Low Volume High Accuracy Genomic Analysis
Using Jenway’s Genova life sciences spectrophotometer together with a TrayCell fibre-optic cuvette enables sample volumes as low as 0.7µl to be analysed with great accuracy and high reproducibility.
Optimised for use by life science research chemists, the Genova is a true scanning UV/Visible spectrophotometer incorporating a number of pre-programmed methods for DNA/RNA and protein analysis. Measurement of DNA concentrations and purity ratios can be obtained using the wavelengths recorded at 260 and 280nm or 260 and 230nm, with optional correction at a third wavelength. The purity scan gives a clear, graphic display of DNA purity.
The TrayCell cuvette with integrated beam deflection and fibre-optic cables has two caps creating light paths of 1mm or 0.2mm – equivalent to a ‘virtual dilution’ of 1:10 or 1:50 when compared to measurements with a standard 10mm cuvette. The volume range for TrayCell is as low as 0.7–5µl, compared with a
lowest sample volume of 10µl using a standard cuvette. After measurement, samples are simply wiped from the TrayCell’s optical window while the cuvette remains in place in the instrument, thus saving time and ensuring that the aperture remains in an identical position in the light beam.
The Jenway Genova and TrayCell cuvette are ideal partners for protein analysis and determining the concentration and purity of nucleic acids within a wide range of biological samples, in particular for applications including clinical biopsy samples where only very low volume samples are available.
In addition to providing the programmes and calculations required by life scientists, the Genova offers all the flexibility of a standard spectrophotometer including photometric mode, use with standard and long cuvettes, and the option of accessories such as sipper pumps and heated sample chambers. PC software for data acquisitions is also available.

Spectrometer Detects Liquid Contraband in China
60 Samples in 60 Minutes The SPECTRO ARCOS ICP Spectrometer
Ocean Optics the industry leader in miniature photonics, has supplied ten QE65000 scientific grade spectrometers to the Third Research Institute of the Ministry of Public Security, Shanghai. The spectrometers have been integrated into demo units of the AY01-01 Rapid Liquid Contraband Detector, which uses Raman spectrometry to detect a number of liquid and crystal contraband substances.
Currently deployed in various airport locations and border crossings with Vietnam, the QE65000 enables the AY01-01 to detect explosives, drugs, dangerous chemicals and other hazardous liquids or transparent crystals. The device is currently capable of differentiating between up to 200 different compounds, with the speed and accuracy of Raman spectroscopy. Its use is expected to expand beyond airports and borders to large public gatherings such as conferences and sporting events. Unlimited language options make it suited to global use.
When choosing a spectrometer for the AY01- 01, performance, speed and accuracy were the Institute’s highest priorities. As it will be used by security and event personnel to screen thousands of people in a short period of time, it was critical that the device be very fast, simple, and convenient to operate with minimal training.

The highly sensitive QE65000 modular spectrometer can achieve up to 90% quantum efficiency (defined as how efficiently a photon is converted to a photoelectron) with high signal-to-noise and rapid signal processing speed. Its high-speed electronics have been designed for considerable flexibility in connecting to various modules and external interfaces through USB 2.0 (backwards compatible to USB 1.1) or RS-232 communications. It is a popular choice for Raman analysis and other low-light level applications such as fluorescence, DNA sequencing, thin film reflectivity and astronomy.
