Difficulties with calibrating UV-Visible instrumentation like HPLC detectors and spectrophotometers that use flow or microcells are overcome with the new GxP GoldR Traceable Liquid Standards marketed by Stellarnet UK.
A typical problem is that most HPLC detection is done in the UV region, where calibrations made (in the visible) with conventional glass neutral density filters may not be valid.
Similarly spectrophotometer calibrations made at full aperture may not be acceptable when the beam is masked by flow cells or microcells.
These new standards enable a holistic approach to instrument qualification by allowing calibration using the same flow cell, sipper system or other sampling accessory used in the actual analysis.
Different sets of standards are available to check wavelength accuracy or absorbance linearity just in the UV region, or in UV and visible regions.
Traceable to NPL and NIST Certified Reference Materials, they are produced and supported by one of the UK's leading authorities on instrument qualification and validation and come with free software to generate calibration certificates for convenient documentation.
The package also includes an operational SOP for the correct application of the standards and a syringe with HPLC compatible fittings for easy handling.
