Gas analysis - Import export

Knight Optical can offer Gas Cells for use within the Chemical Analysis. We supply a range of Gas Cells for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers within the chemical analysis industry. Gas cells are used in spectroscopy for identification of the contents of gases. The path length and window material are chosen for analysis of different concentrations and types of gas. Depending on the types of gases being analysed, the windows in a gas cell can be made from NaCl, KBr, CaF2, BaF2, or ZnSe and will be chosen depending on bandwidth, to meet the customer’s application. All our Gas Cells are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory

A broad variety of gas transmission cells are : Gas Cells analysis of gas & vapour phase components in IR optical spectroscopy. These range from short path length gas cells for percent level concentration measurement, to long path length gas cells for part-per-billion concentrations. Options include fixed and variable path length gas cells, as well as ambient temperature and heated gas cells. The windows that can be used with the gas cell include NaCl, KBr, CaF2, BaF2, or ZnSe infrared transmission windows, which are mounted in an optical spectrometer. Knight Optical supply high quality Gas Cells optical components made to our exacting specification. For more information read the PDF

Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5µm. Sapphire is birefringent and if its use is for critical optical application then the crystal might have to be cut along the zero degree plane, or C-Cut. Random cut is usually cut along a plane that is 60° off-axis as the growth in this direction is the easiest to grow. Random cut is anything that is not the C-Cut angle. Sapphire can fluoresce depending upon the concentration of other minerals within the lattice, for example Iron (Fe) or Chromium (Cr). Clear Sapphire might fluoresce orange when illuminated by UV light if impurities are in the crystal. Fluorescent free Sapphire has to be grown from 'pure' feedstock and seed and in an environment that cannot place impurities into the lattice. Click PDF link to read more …...

Adoption of SF6 alternative gases increases the maintenance and analysis burden on utility staff, requiring multiple analysers to fulfil test and analysis procedures. This requires increased levels of capital budget; increased time to undertake maintenance tasks; resulting in greater inefficiencies onsite. The EMT Zerowaste Rapide Eco+ solves this problem by fulfilling all measurement requirements in one, simple, portable device. Built on the existing market leading EMT Rapide+ platform, Eco+ is the world’s first 4in1 analyser for the measurement of SF6, Novec 4710, Novec 5110 and Dry Air insulating gas applications.

Preparation is key when it comes to SF6 gas analysis. Ensuring the analyser is within calibration is fundamental to safe operation, compliant measurement and accurate testing. Our Verify NIST traceable verification gases can prove the instrument is in specification and valid for use in accordance with ISO9001 requirements for controlled measurement equipment. EMT SF6 gas verification products utilised during operation provide continued assurance that the analyser is performing as it should be, that the measurements shown are accurate, and that these are in line with the measurement values and tolerances of the supplied gas.

Polyflon offers high quality, bespoke thermoformed tubing, tube assemblies and thermoformed thin film diaphragms. Custom 2D tube shapes can be formed using in-house tooling; pre-formed articles can then be finished with flanges, flares, cuffs, or plugs. Specialist markets for our thermoforming and assembled products include pharmaceutical, bio-tech, instrumentation, environmental monitoring & analysis, oil & gas and semiconductor. Most materials satisfy FDA regulatory requirements and enjoy USP Class VI approval.
