Tender Results of National Physical Laboratory

Optical Frequency Comb-Comparison of optical frequency standards is essential for verifying that the clocks both locally and remotely at other national metrological institutes all agree to within their quoted uncertainties. These quoted uncertainties can be as low as ~1e-18, and so agreement between multiple clocks all operating at this level is required to verify that uncertainty. Remote clock comparisons at NPL, or between NPL and other European NMIs, are only possible at this uncertainty using optical frequency com...

CAN: Procurement of GHz BW Oscilloscope-The National Physical Laboratory [NPL] requirement is for an Oscilloscope to automate collection and measurement of waveforms and device responses. Amongst other applications the purpose of the instrument is to measure and record rise time and sub-nanosecond switching times of novel semiconductor devices. The Asset must be standalone and bench or rack mountable and controllable through ethernet and GPIB/USB (optional). The Asset must be capable (either as supplied or upgradeable) of receiving...

CAN: Procurement of Condensation Particle Counter (CPC) device-The National Physical Laboratory (NPL) requirement is for the procurement of a FTIR gas analyser that can analyse a comprehensive list of GHG and atmospheric pollutants with high sensitivity (possibility for ppb level measurements), high flexibility (ability to build own reference spectra through software) and the ability to measure gas matrices with temperatures from ambient to ~180°C, and up to 40% water vapour Content.

CAN: Procurement of Condensation Particle Counter (CPC) device-The National Physical Laboratory (NPL) requirement is for a Condensation Particle Counter (CPC). This instrument is to be used in both laboratory and field measurements. The device will require a concentration range up to 100, 000 particles in counting mode. Due to the varied nature of the measurements this instrument will be used for it must use water as a working fluid and be easily transportable. It must therefore have an internal pump.
