Systems and methods are described to provide speciation of silicon species present in a remote sample for analysis. A method embodiment includes, but is not limited to, receiving a fluid sample containing inorganic silicon in the presence of bound silicon from a remote sampling system via a fluid transfer line; transferring the fluid sample to an inline chromatographic separation system; separating the inorganic silicon from the bound silicon via the inline chromatographic separation system; transferring the separated inorganic silicon and bound silicon to a silicon detector in fluid communication with the inline chromatographic separation system; and determining an amount of one or more of the inorganic silicon or the bound silicon in the fluid sample via the silicon detector.

Gas chromatograph-mass spectrometer comprising an ion source, the walls of which are realized or covered with at least one layer of graphene. Thus realized, the gas chromato graph-mass spectrometer proves to be particularly suited to the analysis samples containing hydrogen in addition to the substances to be analyzed. This situation generally occurs when the mass spectrometer is coupled to a gas chromatograph that utilizes hydrogen as the carrier gas.

The present invention relates to dialysis based in vitro drug release study method which mainly involves the use of a dialysis cartridge (A), a dissolution vessel (B), a receiver media vessel (C) and tubing's on the inlet and outlet ports (D, E, F, G) of the cartridge. When the pharmaceuticals complex dosage form is added to the dissolution vessel, diffusion of the soluble drug through the membrane of the dissolution cartridge assists in determining the release of drug from the complex dosage form. This study can be done by various methods as required by the complex dosage form. If the dosage form needs to go through dissolution followed by diffusion, the setup as described in Experiment 1 is arranged and the study is performed accordingly and if the dosage form needs to go through diffusion step only, the setup as described in Experiment 2 is arranged and the study is performed accordingly.

A sample extraction device and a desorption device for use in gas chromatography (GC), gas chromatography-mass spectrometry (GCMS), liquid chromatography (LC), and/or liquid chromatography-mass spectrometry (LCMS) are disclosed. In some examples, the sample extraction device includes a lower chamber holding a sorbent. The sample extraction device can extract sample headspace gas from a sample vial by placing the sorbent inside the vial and creating a vacuum to increase recovery of low volatility compounds, for example. Once the sample has been collected, the sample extraction device can be inserted into a desorption device. The desorption device can control the flow of a carrier fluid (e.g., a liquid or a gas) through the sorbent containing the sample and into a pre-column and/or a primary column of a chemical analysis device for performing GC, GCMS, LC, LCMS, and/or some other chemical analysis process.
