The aqueous solutions, namely, PBS, PEG-PLACL in PBS, TA, [TA.sub.EN], [TA.sub.AD], [TA.sub.EN+AD], and EM, had a higher level of electrolytic conductivity
than the oil sample.
Abstract: Complex photometer described in the paper is a portable device with which it is possible to determine simultaneously both the concentration of certain chemical species in water as well as its electrolytic conductivity
. The device can be used for the analysis of independent samples that are found in glass tubes, or of water in displacement through the flow cells using for measurements the flow injection analysis (FIA) (Flow Injection Analysis).
The model CSX2 is a two-electrode sensor that measures electrolytic conductivity
at a range of 1.0-50,000 oS.
is the measure of the mobility of the ions present in the solution.
increases at a rate of approximately 1.9% per [degrees]C increase in temperature.
Induced polarization measurements on cores retrieved from the columns show that the real component of the complex conductivity, a measure of mainly the electrolytic conductivity
, is greater in magnitude for both the saturated and unsaturated zones of the diesel-contaminated column in comparison to the uncontaminated column.
These include the atomic emission detector, the electrolytic conductivity
detector, and the electron capture detector.
The stability of solutions having an electrolytic conductivity
, [kappa], of 5 [mu]S/cm to 100 000 [mu]S/cm packaged in glass screw-cap bottles, glass serum bottles, and glass ampoules was monitored for 1 year to 2 years.

The expanded capabilities include new injectors, an electrolytic conductivity
detector, an integral valve oven for gas analysis, and an automated on-column sample enrichment for headspace analyses.
