Simple method for determining cell and hydrocarbon concentration during fermentation

A simple method for determining serum copper.

The determination of serum copper is of value in a number of metabolic studies, particularly in the investigation of the anemia of chronic infection. Presented here, together with illustrative data, is a method for determining copper in serum, based on the direct extraction of copper carbamate from serum with isoamyl alcohol. Burch et aa. in their method for serum iron have demonstrated that su...

A simple and rapid method for determining blood ammonia levels.

Blood ammonia levels in patients with various liver diseases were determined quantitatively by a simple and rapid method using the Amitest Meter System. The results were compared to those obtained by an enzymatic method and were well correlated. This simple Amitest is also useful in animal experiments, particularly when there is a need to determine blood ammonia levels serially. This paper test...

A Simple Method of Determining Pre-Diabetes

A simple formula for determining pre-diabetes (the very early stage of diabetes mellitus) was derived from the model of Ackerman et al. [Bull Math Biophys 1965; 27: s21-37] for very smoothly varying time course patterns of blood glucose level. The natural period of blood glucose level in a healthy subject calculated using the formula was in good agreement with the value obtained by computer work.

Rapid Stick Method for Determining Blood-glucose Concentration.

Method for Determining the Concentration of Unknown Combustible Gas †

It is known that catalytic sensors have different sensitivities to different combustible gases. Usually gas analyzers are calibrated by methane and not suitable for measuring other flammable gases. Correction is needed to get real concentration of other gases. In this paper it is shown that sensor sensitivity to one particular gas alters with sensor temperature and each gas has its own rate of ...
