Abstract:
Increased stability of derivitization agents on the surfaces of packing material used in choromatography is described. In particular, the stability of the organosilanes on silicia surfaces used in chromatography is increased, thereby creating a more durable coating of organosilanes. By increasing its stability, the organosilane entity becomes more resistant to de-bonding and the durability of the underlying surface is enhanced against dissolution. Thus, chromatographic separations are able to be performed at higher and lower pH ranges and higher temperatures. The stability can be increased through attachment of polydentate silanes which are either pre-polymerized and then surface bonded or can be bonded first and then cross-polymerized afterward, yielding a polymerized polycarbosilane backbone that is very stable against hydrolytic cleavage conditions.
A convenient and efficient method for heating or cooling the mobile phase fluid of a chromatographic system prior to its entry into the chromatographic column is described. The “preheating” or “precooling” process is carried out using an apparatus containing a short length of tubing where the mobile phase is heated or cooled. The heating or cooling is performed using a heating or cooling element that is in intimate thermal contact with the exterior of the tubing. The temperature change of the mobile phase is measured downstream by a non-invasive, low-mass sensing element on the exterior of the tubing. With a low mass heating or cooling element, the device can be very responsive and allows for rapid equilibration and convenient temperature programming of the mobile phase. This configuration also requires only a short mobile phase contact time, is non-invasive, adds no dead volume, and allows for use of columns over a wide range of internal diameter, flow rates and temperatures.

Abstract:
Methods for the solvent extraction of organic analytes from a sample are provided. An organic solvent system is used to extract analytes under elevated temperatures and pressures above 100 psi but below supercritical conditions in short times and with low amounts of solvent. The extracted organic analytes are then removed by flowing a purge fluid through the extraction cell, the cell being maintained at a constant volume throughout the extraction and purging, afterwards the analytes being analyzed.
Device And Method For Connecting A Fluid Conduit To A Receiving Fitting

F16L 1700
US Classification:
285354
Abstract:
A fitting provides a means of making a union between a tube and a female fitting with low dead volume and without the use of tools. The fitting is comprised of a tube member that is pressed into the female fitting to automatically remove dead volume. The tube member is pressed into the fitting by a spring with the appropriate tension to hold the tube member against the expected pressure. The fitting also is comprised of a two piece nut assembly. The forward nut compresses a ferrule to create the high-pressure seal. The rearward nut is attached to the forward nut and provides compression and a holding means for the spring.

International Classification:
G01N 30/30
Abstract:
Certain configurations described herein are directed to gas chromatography devices. In some instances, the gas chromatography devices may comprise at least one heating device which can be moved along a chromatography column to provide a thermal gradient to the chromatography column. In other instances, the gas chromatography devices may comprise a heating device that can receive a moving chromatography column to provide a thermal gradient to the chromatography column. The gas chromatography devices may be configured as portable devices which can be used to perform remote analyses.
