A high power laser-induced acoustic desorption (LIAD) probe is provided for desorbing neutral molecules from a sample analyte on a target into a mass spectrometer for subsequent ionization.

High power laser induced acoustic desorption probe

In acordance with the teachings of the present invention, there are provided mathods, gels, and transferring devices for loading gels. The mathods and devices of the present invention involve the use of ultra-thin, miniature, disposable, slab gels for the quick, inexpensive and high resolution analysis of polynucleotide samples.

Miniaturized disposable gels for DNA analysis

In accordance with the teachings of the present invention, there are provided methods, gels, and transferring devices for loading gels. The methods and devices of the present invention involve the use of ultra-thin, miniature, disposable, slab gels for the quick, inexpensive and high resolution analysis of polynucleotide samples.

An apparatus for use in determining a thermal characteristic of a specimen includes first and second chucks for engaging two regions of the specimen, a first chuck mounting mechanism for supporting the first chuck in relatively fixed orientation, and a second chuck mounting mechanism. The second chuck mounting mechanism supports the second chuck in relatively movable orientation relative to the first chuck to permit variations in the spacing between the first and second chucks occasioned by thermal variations in the specimen. A base supports the first and second chuck mounting mechanisms. A laser is provided for heating a third region of the specimen lying between the two regions to a different temperature than the two regions. An infrared detector is provided for detecting radiation emitted from the third region. The base, the first chuck mounting mechanism, the first chuck, and the second chuck together comprise a fluid circuit for circulating a fluid through the base, the first chuck mounting mechanism, the first chuck and the second chuck.
