This study is a beautiful example of DHPLC technology application and shows an alternative tool to current strategies of SNP detection based on genotyping array.
|When Single Dimension GC Separations Fail: Exploring Real World Applications for Comprehensive Two=Dimensional GC (GCxGC)|
Joe Binkley, Elizabeth Humston-Fulmer, David E. Alonso, and Lorne Fell
Examples will be highlighted for food/flavor/fragrance, metabolomic, and petrochemical application markets. The advantage in number of compounds detected and overall quality of their mass spectral library similarity scores, as compared to one-dimensional methods will be clearly demonstrated.
|Busted! First Detection of Steroid Hormones in Pacific Walrus Bones|
Charapata P, Horstmann L, and Misarti N
The Pacific walrus (Odobenus rosmarus divergens) is a candidate species for the Endangered Species List because Arctic sea ice has declined significantly in the past decades. This project focuses on validating a method for extracting steroid hormones from archaeological, historical, and modern bone creating a baseline of hormone levels during different climate regimes.
|Uncertainty estimation of an analytical method for analysis of fumonisin B1 in four types of rice intended for consumption human|
Petrarca, M.H.; Rossi, E.A.; Sylos, C.M.
The expanded measurement uncertainty of a sample preparation method based on QuEChERS procedure for the determination of fumonisin B1 in four types of rice, using HPLC-FLD after precolumn derivatisation with ortho-phthaldialdehyde, was estimated from in-house validation data.
|Forced Degradation Study of Expired and Marketed Tablets of Amlodipine by RP-HPLC|
Manisha Puranik*, Monilisha Varma
The objective of the current study was to develop simple, accurate, sensitive and stability indicating RP-HPLC method for the determination of per cent drug remained of Amlodipine besylate in the presence of its degradation products in bulk drug, expired tablets and tablets whose expiry date has not been exceeded.
|LC-MS/MS METHOD FOR THE QUANTIFICATION OF PITOFENONE IN HUMAN PLASMA|
B.M. Gurupadayya, S. Sharfuddin and R.S. Chandan
We developed LCMS/MS bioanalytical method for quantitative estimation of Pitofenone HCl in plasma is simple, sensitive, accurate, precise, and selective. Percentage recovery shows that the method is free from interference of matrix. The analytical method presented here has proved to be useful for investigation of the characteristics of Pitofenone in human plasma in pharmacokinetic and pharmacogenetic studies.
|"In-vitro studies on hydroxamic acid- CT DNA binding" |
In vitro studies of five the interaction between five different derivatives of hydroxamic acids, N-phenyl 2,4dichloro phenoxybutyro, N-m-tolyl 2,4 dichlorophenoxyglutero, N-m-tolyl-4-chlorophenoxyaceto, N-m-chloro-phenyl-tertiarybutylbenzo and N-p-tolyl-iso-valero hydroxamic acids and calf thymus DNA was investigated under simulated physiological condition.
|Validation of HPLC analytical method for determination of biogenic amines in agricultural products|
Hyeock Yoon, Jae-Hyung Mah
An analytical method was validated for the quantitative determination of biogenic amines (BA) in agricultural products. The validation results fulfill AOAC criteria and recommendations. This method has been applying to analyze BA in agricultural products for a total dietary survey in Korea.
