Abstract: A gas chromatographic method and apparatus are provided wherein a reservoir system including at least one reservoir is utilized to collect each component as it elutes from a chromatographic separation column. Immediately after collection of each component, a constant flow of carrier gas is allowed to pass into the reservoir system to carry each component to a detector. According to another aspect of the invention, a method is provided which employs a reference gas mixture in conjunction with the reservoir system to check calibration of a gas chromatography system.

Abstract: Acid or alternately base species concentration in aqueous and non-aqueous samples is quantitated, in the presence of interfering ionic salts, using most preferably differential conductivity detection combined with ion-exchange derivatization, wherein characteristically the acid or base species is derivatized to water, and blended indistinguishably in a required aqueous carrier phase, and the interfering salt(s) is derivatized to a distinguishable hydroxide or acid derivative(s). Using the preferred mode of detector read-out, the calibrated peak of the conductimetric response of the salt derivative(s) is compared to the peak of the conductimetric response of the sample and the response differential is displayed and used to predict the acid or base species concentration. The salt(s) concentration (with some exceptions) may be simultaneously predicted since it is proportional to the first mentioned peak. The technique has utility with respect to acids and bases broadly, and most advantageously is used with respect to strong and moderately strong acids and bases of a pK.sub.a and pK.sub.b value, respectively, of about 2 or less.

Abstract: The invention relates to an insulated-gate field effect transistor which is adapted for detecting and measuring various chemical properties such as ion activity in a solution. The device has a chemically sensitive layer which overlies a portion of a substrate other than that covered by the gate insulator. When this chemically sensitive layer is exposed to a solution or other substance, the electric field in the substrate is modified which changes the conductance of the channel between a source region and a drain region. The change in conductance is related to the chemical exposure and can be detected with a current meter.

Abstract: A simple, rapid anion-exchange column chromatographic technique is used to determine the presence of fractions of proteins and enzymes in human serum by separating the fractions on the basis of their net electrical charges. Samples of serum of unaltered ionic strength, layered on mini columns of an ion exchange agent previously equilibrated to a low ionic strength similar to blood serum with a buffer solution, are eluted stepwise with an appropriate buffer solution having different ionic strengths at each step. Elution of the samples is without previous dialysis or other ionization treatment. Column effluents are assayed for protein content or enzyme activity by conventional means, e.g., spectrophotometric analysis. Evaluation of sera from patients utilizing these methods reveals protein fractions or isoenzyme patterns which identify specific diseases associated with the protein or isoenzyme pattern.

Abstract: A chromatographic system including cassettes, each containing a separating column which is connected at each of its ends to a coupling piece having both of its ends in the form of conical surfaces on the outside of the cassettes. These conical coupling surfaces may be connected to complementary-shaped conical fittings in a fluid-tight manner to connect the inlet and outlet ends of the column of the chromatographic instrument lines such as, for example, the sample injector, stream splitter, backflushing inlet and outlet lines, detector and auxiliary gas flows. A special connection fitting allows the direct connection of the conical coupling surfaces of two column-containing cassettes, as well as connection to other parts of the chromatograph between the columns. Thus, the separating column cassettes may be utilized as components of various relatively simple and complex chromatographic systems.
