Human vs Machines: Hardness Testing with the AMH55

June 22, 2022

Does automated hardness testing software really provide that much of an advantage over manual methods?

Pesto can trace its roots back to ancient times, though it really only started taking off in North America in the 1980s and 90s. Though the primary base is consistent, with pine nuts, basil, and olive oil, individual recipes vary. As canned and bottled pesto became more accessible, individual manufacturers developed their own unique flavor profiles. While these recipes are usually trade secrets, the power of GC×GC TOFMS can tease apart some of the differences.

Calming Crude Oil with the CHN828

March 18, 2022

All a refinery can do is operate their facilities in the most efficient and optimized manner. Doing that, however, requires an accurate way to monitor their process.
