Description
Type: Lamp Calibration Accessory
For Use With (Equipment): Evolution One/One Plus Spec
Unit Size: Each
The mercury lamp is the primary standard recommended for testing wavelength accuracy by the USP, PH.EUR, JP, TGA, WHO, ASTM (E275-67), and other internationally recognized testing protocols. The fundamental emission lines of mercury are a physical property, and therefore require no traceability. Because the emission lines of mercury are very narrow, the accuracy of the instrument is tested to the highest possible tolerance. The effective spectral bandwidth of the instrument can also be measured by measuring the full width at half maximum of a mercury emission peak scanned by the instrument. The mercury lamp accessory removes the need for both holmium oxide liquid and toluene in hexane standards when performing routine performance verification testing to comply with the requirements of pharmacopoeias. The lamp also allows you or one of your trained engineers to calibrate Evolution spectrophotometers exactly as they were calibrated in the factory following service to the optical bench. Uses seven mercury lamp lines from wavelength 253.65 to 810nm A unique calibration curve is used for every spectral bandwidth (SBW) available with the spectrophotometer Calibration at 1.0nm SBW is performed and stored independently of the calibration at 2.0nm SBW. Save time, save money, save effort The lamp installs permanently into the Evolution Pro spectrophotometer, and when needed in the Evolution One/One Plus spectrophotometers. It is turned on and off by clicking a box in Thermo Scientific INSIGHT Pro software. Installing a mercury lamp saves time and effort when performing routine performance verification tests. It also saves you money and effort by eliminating the need to maintain and recalibrate or recertify holmium oxide and toluene in hexane liquid standards on a regular basis.INSIGHT Pro software uses the mercury lamp to fully automate the tests for:.
• Wavelength accuracy
• Wavelength precision (wavelength repeatability)
• Spectral bandwidth (1 nm setting) Applications: Chemicals, Food & Beverage, Industrial QA/QC, Pharmaceuticals
