The AnswersYouNeed for FlavorAnalysis The power of processor control, the selectivity of our nitrogen-phosphorus detector, the high resolution provided by glass capillary columns with an all-glass dual mode injection system... just what you expect from Hewlett-Packard. —* Whether it is analysis of food, herbicides, sedatives, fatty acids or more routine work, the HP 5840 Gas Chromatograph brings new analytical power into your laboratory. The chromato/ grams above result from a
sample of yeast extract and demonstrate the re sults of a normally difficult analysis. The small insert shows normal FID response to this sample, whereas the large chromatogram provides quick identification of the N-containing compounds allowing the analyst to focus his ef forts on the peaks most likely to cause unpleasant taste and odor. With a Hewlett-Packard answer machine, the difficult analysis becomes routine. 43606
