Carrier-Based Ion-Selective Electrodes and Bulk Optodes. 1. General Characteristics.

Publisher Summary This chapter discusses the chemical analysis of microbial cells. The preparation of material for analysis is discussed, because changes in the chemical composition of cells may occur as a result of the washing and storage conditions used. Wet- and dry-weight determinations of bacterial samples and assay of total cell numbers are described, because analytical results must refer to one or other of these values. Selection of an analytical procedure is a subjective process, because the number of suitable methods is large and each will have different merits and defects. Primary considerations are sensitivity, specificity, reproducibility, and absolute accuracy. Automatic methods for performing biochemical analyses, already widely accepted in hospitals and in industry, are beginning to make their way into the research laboratory. All automatic analyzers developed so far may be classified as either “continuous-flow” or “discrete” types. All of them use colorimetric methods exclusively and contain some form of automatic colorimeter for final read-out. The first and best-known is the Technicon “AutoAnalyzer,” which is of the continuous-flow type.

A chromatographically useful packing is prepared by immobilizing 8-hydoxyquinoline on Porasil. This material, whose capacity is about 50 ..mu..equiv/g, behaves with an efficiency of about 0.2 to 0.5 mm/theoretical plate but is capable of separating such similar metal ions as Co-Ni, Cd-Pb-Zn, and La-Gd-Yb at trace levels employing both isocratic and continuous gradient elution. On a fundamental level, the relationship between solution chelate stability and chromatographic behavior is described. 9 figures, 2 tables.
