T he V-600 UV-Vis/NIR inst r uments are provided with a “Validation' software package as part of the Spectra Manager Il software package. This Validation software provides many performance tests that can be used to evaluate the continued performance of a UV-Vis instrumen t . When utilizing a UV-Vis spectrophotometer， i t is often desired to obtain a confi r mation o f the instrument performance by conducting instrument qualification tests. The V-600 Instrument Valid a tion software package contained within the Spectra Manager Il software provid e s a set of packaged a n alysis functions to verify that t he instrument is performing to design specifications. The ‘'Pass/Fail' criter i a are established for each instrument in the V-600 series， based on the performance specifications for each instrument. This software can utilize ‘internal'or ‘intrinsic'standards and can also include external standards ， with performance specifications which are t raceable to NIST or some other recognized author i ty. Figure 1 outlines the various performance tests that can be selected within the software. The qualification tests that do not require external standards have been checked within the displayed software dialog. The unchecked quali fi cation tests require other external stand a rds and these can be obtained through Jasco by specifying the external standards kit. Speci f ic tests required to conform to standards established by US Pharmacopeia (USP)， the European Pharmacopeia (EP) Japanese Pharmacopeia (JP) or the Japanese Industrial Standards (JIS) can be selected， or， individual tests can be selected from the list by the user performing the validation tests. The tests are easily performed and the only required user input is the l isting of the Photometric Accuracy values (Figure 2) and the Photometric Repeatabi l ity values from the selected external standards. All other performance tests have speci f ied va l ues applied according to the i nstrument type and the required instrument parame t ers are specified dependent upon the individual test procedure (Figure 3). When t he tests are initiated，the software performs each test， telling the user when to i nsert the specific sta n dards for t he performance 28600 Mary's Court， Easton， MD 21601 USA Application Note tests. At the end of the qualification tests， a detailed report， including pass/fail results ， data and i nstrument conditions can be saved in an electronic for m at a n d also printed ou t for inclusion i n an inst r ument notebook (Fig u re 4). Although i t depends upon internal protocol procedures established by the laboratory， Jasco generally recommends performi n g these tests on at least a quarterly or semi-yearly basis. Conclusions： The Spectra Manag e r I I software inc l udes an instrument Validation package that ca n be used to evaluate the performance of a V-600 UV-Vis instrument. These performance t e sts can be sel e cted and performed as needed by a user to con f irm opt i mum performance of the V-600 i nstrument .
