Agilent Technologies has announced that it is replacing the signal-to-noise specification with a new instrument detection limit specification for its 7000B triple quadrupole GC/MS system. The company considered IDL is a better measure of GC/MS/MS performance as it follows guidelines of IUPAC, US EPA and other organisations. IDL calculates typical performance from a series of automated injections for an accurate view of system performance. The Student's t-test is applied to eight consecutive injections of 100 fg OFN using a 99% confidence interval. In addition, the IDL specification confirms the performance of every component in the system from the autosampler through to the detector. The IDL specification of the 7000B system in EI mode is 12 fg OFN.

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.
Cyto-Lite, from Mad City Labs and distributed by Elliot Scientific, is a new illumination source that outputs blue, green and red laser light through a single fibre. The key wavelengths are 405 nm, 532 nm and 640 nm with the system providing complete control over each laser line via a single USB interface and the supplied software. The controller and software streamlines the user interface and allows the characteristics of each laser line to be independently controlled in constant current feedback or constant optical power feedback modes. The on-board DDS sine wave generator and internal 16-bit DAC allow for the modulation and amplitude of each laser line waveform. Low noise operation is achieved by three independent linear regulator power supplies and filtering on each laser line further minimises electronic noise. Robust and safe operation is achieved through multiple layers of laser line protection. Watchdog circuitry maintains stable power supply operation and each laser line has overcurrent protection circuitry.
The NSC1105 from New Imaging Technology is a 1.3 MPixel WDR sensor with a 10.6 µm pixel size, providing a dynamic range of more than 140 dB in a single frame time. Its Native Wide Dynamic Range technology means that it does not require any setting or exposure time control and provides a useful image whatever the illumination conditions. It also benefits from an extended spectral response in the IR range and good low light sensitivity. It is available with the company’s proprietary package which allows easy integration into PCB cards in socket or SMT mounting.
