The GC liner is one of the most important consumables for your GC inlet. GC inlets convert an injected liquid phase sample into gas for transfer onto the GC column. Selecting the wrong liner can lead to incomplete transfer, poor separation, and peak tailing—often incorrectly attributed to the GC system. As a result, you could waste valuable hours on troubleshooting. Join us as we discuss the different liners in our portfolio and help guide you in the selection process.

Today’s demanding GC and GC/MS applications have pushed the boundaries of GC column phase technology. Features such as improved inertness, robustness and low-bleed chemistries are now necessary to meet the needs for lower detection limits and faster analysis time that GC analysts require. While recent improvements in traditional phenylmethylpolysiloxane phases have occurred, very little had been done with another important group of GC columns, polyethylene glycol columns, also known as WAX columns. Since the introduction of DB-WAX Ultra Inert a few years ago, Agilent have also recently introduced new WAX columns, DB-FATWAX UI and DB-HeavyWAX, that are designed to meet the demands of today’s labs. In this webinar, we will discuss the advances in WAX column technology, the benefits of each of these columns, and what applications they may be able to help.

Carrier gas is a necessary component to any functioning gas chromatographic system. The rising cost of helium, due to a global shortage in supply, has forced labs to consider alternatives such as hydrogen or even nitrogen, but is this a smart choice? Does it make sense for your laboratory? What are the common pitfalls or issues that might arise? In this talk we will take out some of the guesswork associated with making this important decision and help you decide if the switch is right for you.

Sample introduction is arguably one of the most important aspects in successful gas chromatography. The vast majority of problems that arise in GC are inlet or "front-end" related. If your sample is not introduced properly to the inlet and column, all bets are off for producing a useful high-resolution chromatogram. In this presentation we will discuss the various types of GC inlets available including when and how to use them.

Whether you are new to GC or have been performing it for years, you may find that things just aren’t /going the way you want them to. There are many pitfalls that can cause problems and in this talk some of the topics we will discuss include:

• Problematic solvents
• The importance of gas traps
• Syringe hygiene
• Front-end maintenance
• Proper conditioning
• Making connections
• Importance of sample preparation

Avoiding these pitfalls can help you achieve long-term reliable results.

This webinar will explore how the new Agilent 8850 gas chromatograph, now compatible with single and triple quadrupole mass spectrometry, can save users bench space, utility costs, and analysis time without compromising on performance. Viewers will see these features demonstrated through multiple applications, including gasoline aromatic composition by ASTM D5769, Total Petroleum Hydrocarbons (TPH), distilled spirits analysis, and more.

Agilent offers high-quality products for Solid Phase Microextraction (SPME) sample preparation. The SPME technique uses polymer phase coated fibers or Arrows to isolate and concentrate analytes from the sample. There are two types of SPME extraction techniques: Headspace (the most used technique) and direct immersion, where the fiber is immersed into a liquid sample. Agilent offers SPME fibers or Arrows in a range of chemistries that can be used with autosamplers or manual injection holders for all application spaces. This presentation will discuss Agilent’s SPME portfolio and offer guidance on phase selections for various applications.
