CHROMATOGRAPHY AND ANALYSIS SYRINGES<br />
Chromatography and<br />
Analysis <strong>Syringes</strong><br />
In the late 1940’s while working in the radiation lab<br />
at UC Berkeley, Clark <strong>Hamilton</strong> developed various<br />
devices, including glove box syringes for handling<br />
radioactive material. By the early 1960’s Clark<br />
learned about additional liquid handling needs in<br />
the field of gas chromatography during a visit to<br />
Perkin-Elmer where he set out and developed<br />
the first micro syringe for accurate sample<br />
injection into GC instruments. In the early 1960’s,<br />
two major gas chromatography companies,<br />
F&M Scientific and Wilkens Aerograph,<br />
approached <strong>Hamilton</strong> Company to produce high<br />
accuracy syringes for the purpose of introducing<br />
exact, small volume injections into their GC<br />
systems. F&M Scientific and Wilkens Aerograph<br />
later became Agilent and Varian, and <strong>Hamilton</strong><br />
continues to provide syringes for manual and<br />
automated injection into their instruments as well<br />
as many other GC and HPLC manufacturers.<br />
