A folio for use with a tablet computer comprises a pair of leafs pivotally coupled together at a hinge with a keyboard carried by one of the pair of leafs, and another of the pair of leafs carrying the tablet computer and defining a cover for the keyboard in the closed configuration. A fixed top stop is fixed to the cover opposite the hinge and extends outwardly from the cover configured to abut to the tablet computer. A sliding shelf is movably coupled to the cover adjacent the hinge and opposite the fixed top stop to receive the tablet computer thereon in the open configuration. Bias means is coupled to the sliding shelf for biasing the sliding shelf towards the fixed top stop.

A portable multi-dimensional gas chromatograph, the gas chromatograph including a carrier gas container, a regulator fluidly connected to the carrier gas container, a dopant chamber containing a reference chemical, at least one pre-concentrator which is fluidly connected to the regulator and the dopant chamber, a first separation column fluidly connected to the at least one pre-concentrator, a second separation column fluidly connected to the at least one pre-concentrator, a first detector fluidly connected to the first separation column, and a second detector fluidly connected to the second separation column.

Multi-dimensional portable gas chromatograph system

A Gas regulator capable of reducing the pressure of a gas supply from thousands of psi to as low as 30 psi with an accuracy level of +/&#x2212;1 psi. The regulator uses at least two oppositely oriented gas stages to reduce the pressure. The first stage performs gross pressure reductions and subsequent stages perform fine pressure reductions. The regulator easily connects to commercially available gas bottles and can easily activate or deactivate gas flow without needing to disconnect the gas bottle. The regulator has a compact design and can provide readings which can be integrated into computer, online, or dynamic systems.

Very small high pressure regulator

A separation column assembly for a gas chromatograph and the like is provided. The assembly is a self contained unit which allows very rapid heating and cooling of the column.
