APPARATUS AND METHOD FOR ANALYSING A SOLID SPECIMEN MATERIAL
An apparatus and a method for analysing a solid specimen material by means of ablating particles of the solid specimen material by laser into a carrier liquid, having: a specimen holder for arranging the solid specimen material covered by the carrier liquid, a laser apparatus for irradiating the solid specimen material to produce a suspension of particles of the solid specimen material and the carrier liquid, an analysis apparatus for analysing the particles, an ablation cell with the specimen holder, having a liquid channel for the carrier liquid and having an entry window made of a material that transmits the laser beam, a supply line for supplying the carrier liquid into the liquid channel of the ablation cell and a discharge line for discharging the suspension of particles of the solid specimen material and the carrier liquid from the liquid channel of the ablation cell into the analysis apparatus.
NON-INTRUSIVE LASER-BASED TECHNIQUE FOR MONITOR AND CONTROL OF PROTEIN DENATURATION ON SURFACES
A method and apparatus for monitoring and/or controlling the extent of denaturation and/or bond cleavages of proteins on any surface (e.g., biological tissues, biofilms, etc.). In one embodiment, a low power laser (e.g., a 5 mW, 362 nm diode laser) is directed through a biological sample to a photodetector. The sample is heated by a set of radiant heaters to between about 220 C. and about 250 C. in a time period of between 10 seconds to 60 seconds. The baseline transmissivity of the sample is monitored continuously throughout treatment of the biological sample via continuous monitoring of the signal voltage detected at the photodetector. Upon detection of increase in relative transmissivity in the biological sample, the heating treatment is concluded and the biological sample is removed for in situ protein identification as part of an imaging MALDI-MS measurement.
Detection apparatus and detection method
A detection apparatus and a detection method are disclosed. In one aspect, the detection apparatus includes a sampling device for collecting samples to be checked. It further includes a sample pre-processing device configured to pre-process the sample from the sampling device. It further includes a sample analyzing device for separating samples from the pre-processing device and for analyzing the separated samples. The detection apparatus is miniaturized and highly precise, and is capable of quickly and accurately detecting gaseous phase or particulate substances, and it has applications for safety inspections at airports, ports, and subway stations.
