For ultraviolet-visible spectrophotometry
, their linearity ranges were observed to be 0.
Due to the nature of spectrophotometry
, a given liquid will have different levels of absorbency at different wavelengths.
Third, serum bilirubin was measured using direct spectrophotometry
rather than the ideal method of high performance liquid chromatography (HPLC).
(DS) is an advanced, modern spectrophotometric technique.
offers a number of advantages, including ease-of-use, precision and speed while requiring only limited sample preparation.
Simultaneous determination of lamivudine and stavudine in antiretroviral fixed dose combinations by first derivative spectrophotometry
and high performance liquid chromatography.
At the optimum experimental conditions of the reaction of the reagent HOTT with mercury (II) in the aqueous solution of pH 4-6, the effective molar absorptivity ([epsilon]) calculated from Beer's-Lambert plot and the Sandell's sensitivity index  of the mercury (II)-complex with and without the use of [beta]-correction spectrophotometry
were found to be 4.
In the current study, we compared COHb results obtained with automated CO-oximetry (Diametrics Medical AVOX 4000) and manual UV spectrophotometry
(Hewlett Packard 8453 UV spectrophotometer) (8).
The carotenoid content was estimated using spectrophotometry
The G7 proof-to-print process is based on the principles of digital imaging, spectrophotometry
and computer-to-plate technologies and is a simple calibration process that allows converters to achieve a visual match between their proofing and printing methods.
Metals are analyzed using direct absorption atomic absorption spectrophotometry
