Pfeiffer Vacuum has developed the HiCube turbo-pumping stations for applications in the fields of research and development, accelerators, analysis and surface physics as well as vacuum process technology, electron beam welding and leak detection systems. The modular design principal offers versatility that satisfies a wide range of requirements in the 35 L s–1 and 685 L s–1 pumping speed range. They offer a combination of a turbo-pump from the HiPace series and a dry or oil-sealed backing pump designed for the user's specific application needs and come fully configured and ready for immediate employment. All connections are consolidated at the rear of the unit, the turbo-pump can easily be removed from the housing and connected to a recipient or system, as all the individual components are easily accessible and oil changes are simple to perform on the rotary vane pumps without the need for any special tools.Pfeiffer Vacuum UKIssue: 21/01 RSN:

nLight has announced the expansion of its Pearl solid state laser platform into wavelengths from 879 nm to 888 nm with increased electrical–optical efficiency and power levels up to 100 W. Power levels up to 100 W are available at 879 nm, 885 nm and 888 nm with the company's PowerCore fibre at 400 µm or 600 µm and the increased operating efficiencies result in significantly less heat. Using Pearl with upper-state pumping of Nd:YAG or Nd:YVO4 enables the design and manufacture of air-cooled diode-pumped solid state laser systems. Due to the single emitter architecture, narrow spectral widths of less than 3.5 nm full width at half maximum can be maintained. nXLT diode technology enables long lifetime, even under harsh conditions with repeated on/off cycles, whilst the PowerCore fibre provides consistent beam quality and power transmission independent of fibre layout and ­movement.

Hamamatsu Photonics has announced its new thermo-electrically cooled NIR modules. The spectrometer modules consist of a palm-top size polychromator with integrated optical elements, an InGaAs linear image sensor optimised for the required wavelength range and a driver circuit and integrated USB interface to allow simple PC connection and data acquisition. The modules are initially offered in two ranges. The C9913GC series features a spectral response range from 900 nm to 1700 nm using a standard InGaAs image sensor and the C9914GB series features a spectral response range from 1100 nm to 2200 nm using an extended response InGaAs linear image sensor. Both modules are supplied with sample software which allows the user to set the measurement conditions, acquire and save data and then display it graphically. Using the USB interface means that no external power supply is required so that, together with its compact size, it can even be assembled into portable ­equipment.Hamamatsu Photonics (UK) LtdIssue: 20/05 RSN:

Phoenix S&T has announced the availability of the SureSpray AutoNano system for nanoLC and direct infusion mass spectrometry analysis of proteins and metabolites. The system, which deploys a 16-nozzle chip, robotically connects a capillary LC column to one of the nozzles in the chip for undisrupted spray during the entire gradient chromatographic run, using an active spray control mechanism that regulates the electrostatic field for a stable spray. For direct infusion experiments, the sample is sprayed directly from the reservoir behind the nozzle. Switching samples is very quick and samples can be loaded by hand or with an optional robotic liquid dispensing system.Phoenix S & T, IncIssue: 20/01 RSN:

Starna Scientific has recently supplied neutral density filters to an leading manufacturer of emissions testing instruments for use in testing vehicle emissions for the Low Emission Zone in London, which comes into force on 4 February 2008. Excessively polluting vehicles will have to pay a daily charge of £200 to drive within this area! With such charges, accurate calibration of the instruments is essential, and the standards set by the Vehicle & Operator Service Agency require calibration with neutral density filters with a tolerance of not more than ±3% from a nominal value. www.starna.com
