A New Technique

A new technique of desorption of non volatile thermally unstable molecules into a supersonic jet has been developped. With this method isolated large molecules are now available for mass spectrometry as well as for spectroscopic studies at temperatures of a few Kelvin, thus avoiding spectral congestion. It could be demonstrated that molecules like tryptophane and retinal could be desorbed with an IR laser pulse without decomposition and be ionized with a second UV laser to form bare molecule ions without fragmentation.

A New Technique

Techniques were developed to enable convenient, high-power image analysis of (ingested) food material. A constant volume of diluted gut sample was delivered to a large microscope slide before being slowly evaporated in still air to leave all particles statically on the same focal plane. Evaporation also allowed a meniscus to develop around each particle, forcing them to separate and thereby preventing overlap and aggregation of particles. Sub-samples were measured under four high-power magnifications (2050, 1290, 510 and 190) to permit precise estimates of size distributions of the very small particles. The techniques developed avoid the need for large ingesta/digesta samples, sieving, and filtering, all of which have limited previous studies.
