performance-proved instruments for GAS CHROMATOGRAPHY
Sample injected directly on column, passes immediately into flame ionization detector, - minimum dead volume.
Separation of high boiling aromatic compounds. Column: 5°/o Silicone rubber SE 52 on Celite. Temperature: 2 min isothermal 200° C; ballistic program 200°-285° C.
WHAT ANALYSTS ALWAYS WANTED: AN INEXPENSIVE BUT EFFICIENT GAS CHROMATOGRAPH THE MODEL F 20 The majority of gas chromatographic problems can be solved with relatively simple apparatus.That is why Perkin-Elmer has decided to produce a well-designed
gas chromatograph at a favorable price, capable of being used for routine analysis, for medical ana biological research, for teaching purposes, etc. We are proud to present the Model F 20 gas chromatograph, because we have reduced costs without sacrificing high performance! Features of this instrument are: 1) Speedy analysis - by means of quick, accurate temperature changes in the range 50° to 400° C. · 2) Exact reproducibility - due to electronically controlled thermostat. 3) Newly developed flame ionization detector gives highest sensitivity with minimum noise, and wide-range linearity.
4) Compact system of sample injection and flame ionization detector provides short sample path. Interchangeable glass or metal sampling tubes are easily cleaned. 5) Accessibility - by opening the hinged cover the oven, the column, and the block containing the sample injection unit and the flame ionization detector are easily reached.
