    • The present invention provides an exhaust gas analyzing system utilizing a mini-diluter method in which measurement accuracy of the exhaust gas analyzing system can be evaluated by the system itself. In the exhaust gas analyzing system, a sampling flow path is connected to an exhaust gas flow path through which gas exhausted from an engine flows to sample a portion of the exhaust gas. The sampled exhaust gas is diluted with dilution gas introduced through a dilution gas flow path which is connected in parallel to the sampling flow path. A portion of the diluted exhaust gas is stored in a sample bag. The diluted exhaust gas in the sample bag is analyzed in a gas analyzing portion, wherein flow rate of the exhaust gas is measured, trace gas with a known concentration is introduced into the exhaust gas flow path upstream from a connecting point located between the exhaust gas flow path and the sampling flow path while monitoring flow rate of the trace gas, diluted trace gas is analyzed in the gas analyzing portion, and total mass of the trace gas calculated from a result of the analysis is compared with total mass of the introduced trace gas to evaluate measurement itself.

    • Device and method for processing biological, biochemical or chemical samples are provided wherein a first multiwell plate is stacked atop a second multiwell plate. The first multiwell plate has x wells arranged in a regular array, each capable of receiving a separate sample. Each well of the x wells has an outlet at a lower surface of the first plate. The second multiwell plate has y wells arranged in a regular array, each well of the y wells being capable of receiving a separate sample, and wherein y>x. The outlets at the lower surface of the first multiwell plate are arrayed to register with corresponding inlets of a subset of the y wells of the second multiwell plate when the first plate is stacked atop the second plate. A mechanism for aligning the first plate to the second plate is provided, as well as transfer indicia for tracking transfer of sample from the first plate to the second plate. Also, a mechanism for sealing,the first plate to the second plate is provided so that samples can be directly transferred between the first plate and the second plate without cross-contamination occurring in open wells of the second plate.

    • The present invention relates to a simple thermal desorption gas introduction interface for sample introduction of volatile analytes into an atomic spectroscopic detector. An injector is connected to the atomic spectroscopic detector via a first port. The injector further comprises a sealed second port for inserting the volatile analyte bound to an extraction phase. A heating block surrounding the injector heats the injector to a predetermined temperature and keeps it substantially at the predetermined temperature. A carrier gas flow of inert gas is provided into the injector through a third port of the injector located in proximity to the second port. An auxiliary gas flow of inert gas is provided via forth port located between the third port and the atomic spectroscopic detector. The volatile analyte bound to an extraction phase is inserted into the injector, wherein the extraction phase is inserted through the seal of the second port for sealed exposure within the injector. The volatile analyte is then rapidly thermally desorbed from the extraction phase through application of the heat and provision of the carrier gas flow and transported to the atomic spectroscopic detector in a gas flow comprising the carrier gas flow and the auxiliary gas flow.
