Abstract: A holder rack has an array of tubular slots that cooperate with a holder to position an absorbent tip of the holder at a predetermined location. The racks fit over well plates to position each absorbent tip adjacent the bottom of a different well in the well plate to extract dried samples from the absorbent tips. The holders are transported in containers having a frame to receive the holders and a lid to keep them in the container. The absorbent tips can extend through a cap to dry, with the cap connected to the holder to enclose the absorbent tips for transport.

Abstract: In a two-dimensional LC system configured to introduce components trapped in a trap column during a fractionation period T into a second-dimension column, separate components, and then detect the components using a mass spectrometer, a data collection unit receives a signal which indicates timing to delimit the fractionation period T, determines the first data item in the fractionation period T, adds measurement start point identification information to the first data item, and stores all the data in a data storage unit. A two-dimensional chromatogram creation unit recognizes the first data item in each fractionation period T from the read data, and create a two-dimensional chromatogram by aligning data so that the first data items will be aligned at the top along an abscissa.

Abstract: If multiple polyvalent ion peak candidates with different valences surmised to be derived from the target compound have been obtained, a mass chromatogram in the vicinity of the retention time of the target compound at the mass-charge ratio m/z of each polyvalent ion peak candidate is generated, and these are overlaid and displayed on the display screen. If the polyvalent ions are derived from the same compound, peaks of similar shape having a peak top near the retention time should appear in multiple mass chromatograms. Therefore, the user can check the displayed mass chromatograms and easily determine whether they reflect a combination of polyvalent ions derived from the target compound (a) or not (b).

Abstract: An in-vial microextraction (IVME) device is a vial with at least a portion of the inner surface having a sol-gel coating that absorbs at least one target analyte. The sol-gel coating is a metal oxide comprising coating that is formed from a tri- and/or tetra-functional metal comprising precursor that condenses to form a gel network. The IVME device can be used to prepare a sample by the contacting of the IVME device with a solution or suspension. An analytical method is enabled where the absorbed analyte from the IVME device is subsequently desorbed with a solvent or solution or thermally desorbed and analyzed using GC-MS or LC-MS or other analytical instrument for separation and detection.
