Colorimetric Analysis. For the synthesized chitin/lignin products as well as for the initial precursors, colorimetric analysis was carried out using the CIE [L.sup.*][a.sup.*][b.sup.*] color system.
Another important parameter in colorimetric analysis is the dE variable, which determines total color change.
SEAL Analytical's SEAL AQ400 discrete analyzer was designed to meet the needs of environmental laboratories of all types using colorimetric analysis
. Based on a high standard of reliability and low detection limits, the discrete analyzer is a true walkaway solution.
For this, she designed a research study using colorimetric analysis
to correlate colour space values with carotenoid content in pumpkins and squash.
Because the clinical characteristics of SASD are very similar to those of other lysosomal storage diseases, differential diagnosis relies on detection of increased urinary sialic acid excretion by thin-layer chromatography of urine (5) and quantification by colorimetric analysis
(6) or ion-exchange HPLC (7).
, Photometric Analysis, Auto-Dilution Colorimetric Analysis
, Titrimetric Analysis and Instrumentation are broken down according to method.
Serum iron was determined by colorimetric analysis
(Roche Diagnostics or Beckman Coulter).
Operators use battery or line power to put the colorimetric analysis
system to work anywhere throughout the process, in the field, or in the lab.
One of our most rewarding moments, however, came as a result of studying the Malloy-Evelyn quantitative colorimetric analysis
, which uses the van den Bergh reaction coupling serum bilirubin with diazotized sulfanilic acid to quantitatively produce the measured dye "azobilirubin" (17).
The presence of glutaraldehyde can be detected by direct colorimetric analysis
