Click here Featured Application Note Column Equilibration in HILIC Mode This ACE Knowledge Note describes how to equilibrate HILIC columns for both isocratic and gradient methods to obtain reliable and reproducible HILIC separations.   GC Microextraction in Syringe and SPME from Plastic Bags Three methods of organic contamination extraction from industrial-grade polyethylene bags using a robotic GC–MS autosampler for detection and identification.   GPC Identification of Insulin Oligomeric States The distribution of insulin oligomers, a critical quality attribute for insulin drug product, is determined absolutely using multiangle light scattering (SEC-MALS).   Sample Prep Fast, Reproducible Pesticide Residue Analysis in Food Perform consistent extraction of pesticides for analytical quantitation in 10 min. The PLE® can dramatically improve reproducibility of results, speed, and cost. Multiclass Multiresidue Veterinary Drug Analysis in Beef This note describes simple pass-through cleanup for vet drug analysis in beef using Agilent Captiva EMR—Lipid, which minimizes lipid and maximizes recovery.   HPLC Characterizing Antibody-Drug Conjugates Antibody-drug conjugates (ADCs) have complex structures, making characterization a challenge. This application note shows how 2D-LC/MS can analyze ADCs fast and easily. A Rugged 4-Min Method for High-Throughput Labs The dilute-and-shoot EtG and EtS LC–MS/MS analysis developed here using the novel Raptor EtG/EtS column easily resolves EtG and EtS from matrix interferences. Hyphenated Analysis of organophosphates using HILIC-ESI-MS Several organophosphates were analyzed by HILIC-ESI-MS. The unique selectivity of iHILIC-Fusion(+) column makes it applicable for the studies in battery industry and environmental monitoring.
