ABSTRACT:
A novel chromatograph is provided. The chromatograph includes an analytical column which is a channel with a rectangular cross-section. Integrated with the chromatograph are a sample collection channel and a restriction channel. The column, sample collection channel, and restriction are all part of a single unitary microstructure. The microstructure is manufactured by irradiating and etching a material subject to synchronized x-ray radiation. The device will either be made of the actual etched material, or the etched material will be used as a mold or model to fabricate the chromatograph. A method of using the device is also disclosed.
