When and Why to Use an Electronic Flowmeter

Flowmeters are often seen as essential tools for gas chromatography labs. But, since modern GC instruments feature advanced pressure controls, valves, and built-in flow measurement software, is it necessary to have a handheld electronic flowmeter device? In this Restek Tip, we share some situations where an electronic flowmeter can be used and look at the benefits of using one instead of your instrument. ----------------------------------------------------------------- Contents 0:00 GC Flowmeters 0:34 Why Use a GC Flowmeter? 1:14 Measuring GC Column Flow 1:35 Measuring Fuel Gases 1:56 Calculating Split Ratios 2:12 Verify Results ----------------------------------------------------------------- Additional Resources Restek Electronic Flowmeter FAQ | https://www.restek.com/faq_flow A Primer on Gas Flow | https://www.restek.com/Technical-Resources/Technical-Library/General-Interest/general_GNAN1402 ----------------------------------------------------------------- Restek Recommended Tools & Parts Restek ProFLOW 6000 Electronic Flowmeter | https://www.restek.com/flowmeter ----------------------------------------------------------------- Connect with Us Comment on this video and subscribe to Restek's YouTube channel today at https://www.youtube.com/user/RestekCorp Website: https://www.restek.com LinkedIn: https://www.linkedin.com/company/restek-corporation/ Facebook: https://www.facebook.com/RestekCorporation Twitter: https://www.twitter.com/Restek

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. In this Restek Tip, we show you how to set up your new LC column. We cover certificate of analyses (CofAs), discuss the different column end-fittings you can use, share how to condition your column for your mobile phase, and finally, we’ll look at how to select an appropriate flow rate for your column.

Optimizing Split Injections

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? In this Restek Tip, we’re going to show you how to optimize your split injections. We’ll start with liner selection, before discussing the importance of split ratios. Next, we’ll focus on optimizing the inlet temperature, and finally, the initial oven temperature. ----------------------------------------------------------------- ADDITIONAL RESOURCES GC Inlet Liner Selection: Split Liners, Part 1: https://www.restek.com/chromablography/chromablography/gc-inlet-liner-selection-part-ii-split-liners/ GC Inlet Liner Selection: Split Liners, Part 2: https://www.restek.com/chromablography/chromablography/gc-inlet-liner-selection-part-iib-split-liners-continued/ How to Choose a GC Inlet Liner: https://www.restek.com/technical-literature-library/articles/how-to-choose-a-GC-inlet-liner-simplify-selection-based-on-injection-type/ GC Inlet Maintenance Guide: https://www.restek.com/technical-literature-library/articles/GC-inlet-maintenance-resteks-quick-reference-guide/ ----------------------------------------------------------------- RESTEK RECOMMENDED TOOLS & PARTS Restek Inlet Liners: https://www.restek.com/liners/ Restek Electronic Leak Detector: https://www.restek.com/leakdetector/ ----------------------------------------------------------------- CONNECT WITH US: Comment on this video and subscribe to Restek's YouTube channel today at https://www.youtube.com/user/RestekCorp Website: https://www.restek.com Twitter: https://www.twitter.com/Restek Facebook: https://www.facebook.com/RestekCorporation LinkedIn: https://www.linkedin.com/company/restek-corporation/
