"WE WERE ABLE TO S T A N D A R D I Z E OUR S A M P L E S I Z E " "We tried several methods of standardizing our sample injections without success," states Mr. Sam Ashworth, Chief Chemist for American Chemical Corporation, Long Beach, California, "But with Hamilton syringes we are able consistently to inject a standard liquid sample of 1 ul and gas sample of 2 mi on all of our injections." In the operation shown above, Mr. Ashworth is making an analysis with an injection of a 1 ul sample of the reactor product to determine impurities. He is using a dual column system with one column at ambient temperature while the other column is at 200°C. The columns are connected with a three-way valve. This operation also has a fraction collector for obtaining fractions for identification by infrared analysis. Hamilton manufactures a complete line of precision syringes from a capacity of 0.5 ul to 500 ul and other related chromatograph equipment.
