LC Leak Checking

Leaks are one of the most common problems users encounter when performing liquid chromatography. Even the smallest leak in your LC system can cause a loss of sample, a drop in efficiency, and break your entire analysis workflow. In this Restek Tip, we investigate the signs of a possible leak and outline the troubleshooting steps you should take if a leak is discovered. ----------------------------------------------------------------- Additional Resources Effective LC Troubleshooting | https://www.restek.com/articles/effective-lc-troubleshooting-symptom-based-strategies-and-solutions Routine LC Maintenance | https://www.restek.com/articles/routine-lc-maintenance ----------------------------------------------------------------- Restek Recommended Tools & Parts EXP Reusable Fittings | https://www.restek.com/search?Ntt=EXP&Ns=bestMatch Restek’s HPLC & UHPLC Columns | https://www.restek.com/c/1119 Restek’s LC Accessories - LC-MS Supplies | https://www.restek.com/c/1122 - LC Autosampler Supplies | https://www.restek.com/c/1118 - Mobile Phase Management | https://www.restek.com/c/1123 - LC Detector Supplies | https://www.restek.com/c/1120 - LC Tubing & Fittings | https://www.restek.com/c/1121 - LC Pump Supplies | https://www.restek.com/c/1124 - Tools & Organization | https://www.restek.com/c/1125 ----------------------------------------------------------------- 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

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/articles/frequently-asked-questions-proflow-6000-electronic-flowmeter A Primer on Gas Flow | https://www.restek.com/articles/a-primer-on-gas-flow ----------------------------------------------------------------- Restek Recommended Tools & Parts Restek ProFLOW 6000 Electronic Flowmeter | https://www.restek.com/p/22656 ----------------------------------------------------------------- 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

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.
