The document describes a drug called Verapamil, which is a calcium antagonist used to treat hypertension, cardiac arrhythmia, and angina pectoris. The drug also shows some prophylactic effects against migraines.

The HPLC method presented here shows the chromatogram of the four common antiasthmatic drugs theophylline, theobromine, caffeine and emprofylline using isocratic analysis on a reversed phase column and UV detection.

This document introduces the detailed steps for analyzing testosterone and its metabolites using HPLC.

This document describes the collection of fractions from an oligonucleotide separation using gel electrophoresis and offline MALDI-TOF analysis. By using the Agilent oligonucleotide kit and Agilent Capillary Electrophoresis system, antisense oligonucleotides can be successfully separated. The Agilent ChemStation software allows for fully automated collection of fractions using signal A as the peak sensor. This method enables further analysis of the separated peaks and determination of the molecular mass.

This document introduces the features of the BENCHMARQ bq2057 series advanced Li-Ion linear charge-management ICs, including 0.3V dropout voltage, dynamic compensation of battery pack's internal impedance, optional temperature-monitoring before and during charge, integrated voltage and current regulation with programmable charge-current and high- or low-side current sensing, integrated cell conditioning for reviving deeply discharged cells and minimizing heat dissipation during initial stage of charge, better than ±1% voltage regulation accuracy, charge status output for LED or host processor interface, automatic battery-recharge feature, charge termination by minimum current and low-power sleep mode.

This article describes the use of high-performance liquid chromatography (HPLC) for the analysis of fat-soluble vitamins. HPLC can separate and detect these compounds at room temperature while blocking oxygen and light. UV-visible diode-array detection provides both qualitative and quantitative data. Electrochemical detection is also a highly sensitive and selective HPLC method. Different food matrices require different extraction procedures, including alkaline hydrolysis, enzymatic hydrolysis, alcoholysis, direct solvent extraction, and supercritical fluid extraction.

This product is a lithium battery charging management IC, which is applied to small portable electronic products. Its features are integrated with high-precision current and voltage regulation, battery status detection, temperature monitoring, charge termination, charge status indication and AutoComp.

Orthogonal methods for protein purification and purity analysis are important to determine with certainty protein identity and purity. The Agilent 1100 Series purification system and the Agilent 2100 bioanalyzer with the Protein 200 Plus LabChip® kit provide an ideal solution that ensures efficient and reliable protein purification and characterization.

This article introduces the Statistical Peak Identification feature in Agilent Technologies' Cerity NDS for Chemical QA/QC, which addresses the complications in traditional peak identification algorithms caused by peak shifts, changes in concentration, and external forces. It provides a more robust quantitation.

This application note describes the methods for measuring protein size and protein expression using the Agilent 2100 Bioanalyzer and Protein 200 LabChip® kit.
