Click here GC-MS Biomarkers in Breath The comprehensive, high-sensitivity screening of disease biomarkers through the use of sampling onto sorbent tubes, automated preconcentration, and GC×GC–TOF MS   LC Bioinert HPLC Analysis of Nucleotides Chromatographic separation of phosphorylated species, such as nucleotides, is highly challenging. Instrument and column inertness ensure successful analysis. Molecularly Imprinted SPE Polymers vs Immunoaffinity for Mycotoxins AFFINIMIP® SPE offers a faster, selective, alternative to immunoaffinity purification for mycotoxin analysis by LC–fluorescence, while producing comparable recoveries. Arsenic Speciation on Hamilton PRP-X100 Organic arsenic compounds added to feed stocks of chicken and poultry pose serious environmental and ecological threats. Aflatoxin Assay Using a Low-Cost Fluorescence Detector An isocratic HPLC method for the analysis of aflatoxins. Uses the DFL-10 ( filter fluorescence detector) with a photochemical reactor to improve sensitivity.   Chiral Chromatography SFC Achiral Separation Utilizing a Chiral Column This application note demonstrates the ability of Daicel’s CHIRALPAK® IA-3 to perform both chiral and achiral separations using SFC and hydrobenzoin as a test compound.   GC Hydrogen Faster Safer Note discusses the benefits of switching from helium to hydrogen for carrier gas in gas chromatography. Analyze More Semivolatile Samples per Shift Using Split Injection Using split injection can increase sample throughput for semivolatiles analysis because it provides faster oven cycle times due to the use of higher initial oven temperatures.     LC-MS Correlation of FcR Affinity Chromatography with Glycan Pattern and ADCC Activity of a Therapeutic Antibody These results confirm that FcγRIIIa affinity chromatography allows fast assessment of biologic activity and glycoform pattern of antibodies.   Sample Prep QuEChERS Approach for Pesticide Residues in Soil The aim of this study was to evaluate the effectiveness of the QuEChERS extraction and clean-up approach for the analysis of 21 pesticides in soil
