1996) was used to derivatize
all the samples, and 2 linear regression curves were made using FFA 16:0 and FAME 19:0 to quantify simultaneously both FFAs and FAME.
The original GC-MS procedure incorporates a 15-min incubation at 60 [degrees]C with N-methyl-N(tert-butyldimethylsilyl) trifluoracetamide to derivatize
the analytes and internal standard.
Methods using a variety of reagents, most often pentafluorobenzyl bromide (PFBBr), derivatize
Three organosilanes (phenyltrichlorosilane, 1-phenyl-4-trichlorosilylbucane, and 1-phenyl-11-trichlorosilylundecane) were used to derivatize
fumed silica with different surface characteristics.
Initial research will look at ways to derivatize
HallStar's patented photostability technologies to create unique ingredients that improve both the utility and feel of sunscreen and sun-protection product formulations.
We therefore concluded that unless cellular material is available in abundance, it is better to separate DNA and RNA first, then derivatize
separately under different conditions.
Amplifex[TM]-Diene Reagent is a reagent that can be used to derivatize
any molecule with a cis-diene system, including compounds such as Vitamin D3 and Vitamin D2 analogs, such as 1, 25-Dihydroxyvitamin D3 and 1, 25-Dihydroxyvitamin D2, among others.
Laboratories that do not derivatize
their samples would likely need to adjust their cutoff values for C16 acylcarnitine following similar validation studies as described here.
Teong Lim, Chairman and CEO, reports that a method for detecting and measuring melamine without the need to derivatize
or modify the sample has been created.
