A discussion on which method is more appropriate for protein expression difference analysis, based on examples of quantified known proteins.

Points for selecting LC columns to improve separation, Part 2. Here, we will focus on column efficiency (N).

This document explains the countermeasures for each step of the solid-phase extraction troubles identified in Sample Preprocessing Troubleshooting Part 1.

We will introduce tips for performing solid-phase extraction and fun experimental examples using dyes for those who are about to start solid-phase extraction.

Starting Here: LC Course ~Intermediate Edition: Efficient Analysis with Chromatographs Tailored to Applications~ When it comes to chromatographs (high-performance liquid chromatography systems), there are various types available depending on their applications. General-purpose analyzers, low-dispersion types, and those with multiple flow paths are just a few examples. The characteristics of a chromatograph significantly influence the analyzable conditions and results. Additionally, using a chromatograph that is not suited for the intended application can lead to inefficiencies, such as prolonged analysis times and unnecessary costs. In this webinar, we will explain the features of each chromatograph, their applications, and their impact on analysis. Program: - Classification of chromatographs - Impact of chromatographs on separation - How to choose a chromatograph based on application

Starting Here: LC Course ~ Beginner's Edition: Basics of LC and Analytical Columns ~ Liquid chromatography (LC) is an essential technology in pharmaceuticals, cosmetics, chemical products, food, environmental fields, and various inspections and tests. On the other hand, you might feel apprehensive, thinking, "Isn't this a complicated technology?" In this webinar, we will explain the basics of LC and the analytical columns that are central to separation. We encourage those who are new to LC to actively participate. Program: - What is chromatography? - Representative separation modes of HPLC - Basics of analytical columns

Introducing a web tool that supports column selection with a focus on selectivity (α) for improving separation in LC column selection.

Rapid and reproducible analysis of high-polarity pesticides without derivatization Waters' Anionic Polar Pesticide Column has been developed to provide a reliable analytical method when combined with Waters UPLC-MS/MS technology. Dedicated columns for applications targeting substances like glyphosate enable excellent retention, peak shape, and separation of a range of anionic polar pesticides without the need for derivatization. We will also introduce the latest tandem quadrupole mass spectrometer used for this analysis. Program - Challenges in the analysis of glyphosate - Introduction of the Anionic Polar Pesticides (APP) column - Challenges (retention, separation, reliability, detection) - Analytical methods and reliability of the APP column - Introduction of the latest tandem quadrupole mass spectrometer
