Mass Spectrometry & Spectroscopy 19 New Software for Users of NMR in Quality Control
In response to feedback from the worldwide user base, Oxford Instruments has provided new features on its MQC range of benchtop NMR analysers. MultiQuant Version 6.1 brings many enhancements that may be customised to fit the needs of the local user through provision of a regional language menu. The new software also addresses the specific needs of a quality control operative to ensure consistent data and performance of the instrument. Making the instrument more straightforward to use was key in the design of the new software. For example, the autotare balance options provide for optimum throughput. This is particularly relevant if the application is for oil and moisture measurement in seeds or when looking at the spin finish (OPU) on fibre. A user no longer has to press any button on weighing their sample prior to measurement. They just place the sample tube inside the instrument and the measurement starts automatically. This is useful when operators routinely have to make measurements more than hundred times in a single day. With all measurements being carried out with an instrument temperature of 40˚C, the software now automatically displays any variations from the set point temperature in red, an immediate and clear warning.
Quality control applications often call for batch analyses. For example, users may prepare a batch of samples to measure consecutively. They have the need to enter sample information then measure each sample in turn. The MultiQuant software now allows this either by adding the details from a list manually in the software, or by copying the whole list from the clipboard directly into the batch facility available in the Analysis section.
After analysis, it is now a simple process to copy results directly from the log file into Excel or Open Office. This is particularly useful for users who need to produce their own reports without going through a LIMS system. Lastly, MultiQuant 6.1 is fully compatible with the MQC Autosampler, speeding sample throughput, especially useful when samples require conditioning at a non-ambient temperature. The Autosampler also allows sample tubes to be automatically tared, moved from the conditioning block to the balance and finally into the magnet for measurement without further user intervention.
Circle no. 49 Excellent Spectrometer Thermal Stability
To maintain thermal stability of spectrometers operating in variable environments, Ocean Optics has released the USB-TC small-footprint heating device. Compatible with the company’s USB2000+ and USB4000 miniature spectrometers, the unit attaches directly to the spectrometer and maintains wavelength thermal stability to within +/-0.025 pixels/ºC. This temperature control ensures accuracy in industrial and other settings where temperature variations can affect spectral performance.
The USB-TC is available with pre-selected setpoint temperatures between 25-55ºC and comes with a 12 VDC, 3A power supply. With constant ambient temperature, the USB-TC stabilises to within 0.1ºC of the final temperature within 30 minutes of power-up. The system will operate in temperatures ranging from 5-40ºC below the setpoint temperature. The USB2000+ and USB4000 are among the most popular miniature spectrometers in the world. Their small-footprint, high-speed CCD-array design is ideal for a wide range of applications. Modular optical bench accessories (entrance apertures, order sorting filters and more) make it possible to configure the USB2000+ and USB4000 for hundreds of different applications.
The USB-TC is available with new spectrometer purchases or as a retrofit option for existing owners of USB2000+ and USB4000 spectrometers. Circle no. 50 ADVERTORIAL
Jenway’s Comprehensive Range of Spectrophotometers
Four Famous Brands Under One Company
Bibby Scientific design and manufacture four internationally recognised brands Jenway, Stuart, Techne and Electrothermal with reputations for product quality and exceptional performance. Bibby Scientific is one of the largest broad based manufacturers of laboratory products worldwide with a UK headquarters and subsidiaries in the USA, Singapore, France and Italy, as well as an associated company in the Middle East.
Jenway equipment offers an extensive range of analytical instrumentation such as electrochemistry products, spectrophotometers and flame photometers. The Jenway range of electrochemistry products offered includes pH, dissolved oxygen, conductivity and specific ions meters.
Visit the Bibby Scientific stand, number 134, at Aralab in Dubai 26th – 29th March 2012 to see a special preview of Jenway’s first variable double beam spectrophotometer as well as a host of other new products.
Circle no. 52
Jenway offer four ranges of visible and UV/visible spectrophotometers which have been designed to suit a wide range of budgets, industries and applications.
The 63 series are entry-level spectrophotometers which are ideal for routine analysis. Models 6300 and 6305 include measurement modes for absorbance, %transmittance and concentration.
The 73 series spectrophotometers are single beam spectrophotometers which use icon driven software and have an improved navigation system. The 7305 and 7315 models use a press to read xenon lamp to provide accurate readings and extend lamp life.
The 67 series spectrophotometers are a range of split beam visible and UV/visible spectrophotometers that possess a host of novel features. These include a colour touch screen, secure multi-user operation, a full range of plug-in accessory modules and flash synchronised scanning which allows the 67 series to achieve scan speeds of 1500nm/min, even when scanning at a resolution of 0.1nm.
Coming soon to the Jenway range is the 6850 which is Jenway’s first variable double beam UV/visible spectrophotometer. The variable spectral bandwidth and integrated user interface make this a very flexible spectrophotometer.
All of the Jenway spectrophotometers are supported by a wide range of accessories which have been designed to increase productivity.
