The Chemical Heritage Foundation (CHF) (52) has a number of clinical chemistry analyzers on display, such as a Technicon AutoAnalyzer
Sampler Unit, in their permanent exhibition in Philadelphia, "Making Modernity.
4]-P (hereafter referred to as DRP) concentrations using a Technicon Autoanalyzer
IIC and methods published by Technicon Industrial Systems (1973a; 1973b; 1976).
Phosphorus and N in the digestate were determined by semiautomated colorimetry (Hambleton, 1977) with a Technicon Autoanalyzer
II (Technicon Industrial Systems, Tarrytown, NY).
Resin was extracted with 100 mL of 1 mol/L KCl and analyzed colorimetrically for [Mathematical Expression Omitted] and [Mathematical Expression Omitted] on a Technicon AutoAnalyzer II (Technicon 1978, 1979).
Resin bags were air dried, extracted with 100 mL of 1 mol/L KCl, and analyzed colorimetrically for [Mathematical Expression Omitted] and [Mathematical Expression Omitted] on a Technicon AutoAnalyzer II (Technicon 1978, 1979).
It required some skill to change the dialysis membrane on the Technicon Autoanalyzer
4]-N), concentrations using a Technicon Autoanalyzer
IIC (Seal Analytical, Buffalo Grove, Illinois) with colorimetric methods (Mulvaney, 1996).
Results were compared with those obtained with the Technicon AutoAnalyzer
II (Bayer/Technicon Instruments) (11) in use in our Brussels laboratory for more than 20 years and periodically subjected to routine external quality control.
Phosphorus was measured with a Technicon Autoanalyzer
II according to the manufacturer's instructions (Technicon, 1976).
In addition, the method was compared with the classical Technicon AutoAnalyzer
method (35), which had been used for decades in our institute (23, 24, 36, 37).
Historically, this group of tests was selected as a basic profile--not for their medical value but because these tests could be performed on the early Technicon autoanalyzers
