HPLC

An overview of the method translation calculators to make conversions from conventional HPLC to high-throughput HPLC and UHPLC.

An interview with Merck's Christopher Welch about high-throughput analysis using MISER chromatography and how it can boost your laboratory's productivity.

Where do you start when you encounter a problem with your LC system?

An automated technique for esterifying fatty acids in canola oil compares favorably with a manual method.

Electrostatic effects superimposed on hydrophilic interactions enables selection or deselection of functional groups for compound isolation.

LC–MS-MS is used to detect compounds relevant for food safety.

A new sample preparation method is described for whole blood sample analysis in clinical and preclinical studies.

What do you do when a peak grows over time?

Octadecyl bonded silica gel (C18) is widely used in solid-phase extraction (SPE), but there are many variations including particle size, pore size, surface chemistry, and carbon loading applications.

A change in the mobile phase strength can be a powerful tool to move peaks in a separation.

Here is a step-by-step approach to investigate the source of ghost peaks in a gradient LC method.

Ghost peaks can be tough to eliminate when minor peaks are important. This case study shows how to isolate the source of such peaks.

This year, many HPLC systems focused on facilitating process development, method transfer, and biological analysis.

This process can improve efficiency in a drug discovery laboratory.

Here's how these new reference standards were characterized.

Microextraction by packed sorbent is a sample preparation technique that can be connected on-line with LC or GC systems.

Can pressure alone affect the appearance of a chromatogram?

Often, what you remember most about your career is the great people you met along the way.

Can pressure alone affect the appearance of a chromatogram?

A high performance thin-layer chromatographic (HPTLC) method was developed for the determination of aflatoxin B1 in cereals.

A high performance liquid chromatography (HPLC)–UV method was developed for the analysis of phenylurea herbicides and applied successfully to the analysis of herbicides spiked in three soft drink brands and tap water.

Tips on what to consider when choosing another column to try and solve a tricky separation problem.
