Tech Tip - General
What You Need to Know About Gas Regulators
Gas regulators are fascinating devices and necessary tools in many chromatography applications. But with many options available and multiple variables to consider, choosing the right one can be a difficult task.
3 Ways to Reduce Your Helium Usage
Helium scarcity continues to be a pain point for gas chromatography. Prices are trending upward, supplies can be hard to source, and it’s a problem that isn’t going to go away.

Optimizing Splitless Injections
Splitless injections excel at trace analyses, but to get to get the most out of a splitless analysis, it’s important to optimize your system. But what should you optimize and what are the benefits?
When performing a split injection, there are several considerations to keep in mind to improve the quality of your chromatography. But what should you change and why?
Connecting GC Columns Using a SilTite µ Union
When you need to connect two fused silica capillary columns, a durable and reliable connection is vital.
Split and splitless are the two most commonly used GC injection techniques. While they share some similarities, each is suited to a particular type of analysis. But how do you know which one to use?
10 Places to Check for GC Gas Leaks
Gas leaks are the bane of every gas chromatographer’s existence. Even the smallest leak can cause a loss in sensitivity, contaminate samples, damage columns and instruments, and lead to a lot of wasted time. So grab your electronic leak detector and join us as we explore 10 places to check for leaks to help keep your gas chromatograph in tip-top condition!
The Importance of GC FID Maintenance
Flame ionization detectors (FIDs) are one of the most common gas chromatographic (GC) detectors. For best performance, they require some routine inspection and maintenance. We’ll discuss some common symptoms that may indicate a need for maintenance and the essential tasks to keep your FID running its best.

What Do You Do with a New LC Column
Before you can use a new LC column to perform analyses, there are a few important steps you need to do to prepare it for its new life in your lab.
Correctly Using a Press Tight Connector
If you’ve ever needed to connect a guard column to an analytical column, or connect two columns together, or repair a broken column, you know how essential it is to have a clean, reliable connection.
Why Are There so Many C18 LC Columns
From end-capped to aqueous, there are a multitude of C18 phases to choose from. But why are there so many? A C18 is a C18, right?
Tech Tip - Sample Preparation
Solid phase microextraction, or SPME, is a fast and versatile sample preparation technique that reduces sample handling and solvent consumption. It can be used for headspace and immersion sampling while producing very clean extracts.
Whether you're performing food, environmental, or clinical analyses, Restek's PAL SPME Arrow can quickly become an indispensable tool. This fast and automated sample preparation technology reduces sample handling, extraction time, and solvent consumption.
QuEChERS is a sample preparation technique that vastly simplifies the analysis of pesticide residues. It's quick, easy, cheap, effective, rugged, and safe. In this video, we'll show you the two primary steps of the QuEChERS method: the extraction of your analytes of interest using extraction salts, followed by the cleanup of your supernatant using dSPE. Let’s get started!
Tech Tip - Standards
Preparing a New Reference Standard for Use
Reference standards must perform at a consistent level each and every time you use them. They need to have the same concentration of analytes, maintain the correct consistency, and be stored and used at the correct temperature.
Sonicating Your Reference Standard
Depending on how you store your reference standards, did you know it’s possible for some of the analytes to fall out of the solution? This will impact the concentration of your analytes, leading to problems with your analysis
