Just last week, the Mars 2020 Perseverance rover landed in the Jezero Crater. Now, for the first time ever, NASA has released footage of this landing. 


To mark this monumental occasion, we’d like to kick off our next installment of The Spectroscopist newsletter with our feature from a team using Raman spectroscopy to search for mixed sulfates in martian soil - a key indicator of biological life. Also in the mix: our Image of the Month on the oldest terrestrial fossil ever found, and two quick hits on detecting tumours in the brain and how tree rings can reveal a millennium of solar activity. 

Enjoy! Lauren Robertson, Deputy Editor

Application Notes
Improved UHPLC separation of fatty acid methyl ester by column coupling

Methyl linolenate and methyl γ-linolenate are separated by coupling 2 YMC-Triart C18 ExRS columns, while by using only 1 UHPLC column with the max. length of 150 mm they could not be fully separated. Read more

Multi-Detector GPC/SEC Analysis of Polysaccharides

Polysaccharides have been used in applications ranging from paper and cotton manufacturing, to bioprinting and bioengineering, to pharmaceuticals, gelling agents in food, and other consumer products. Read more

Analyzing Polymer Solutions Used in Inkjet Printing Using GPC/SEC

Inkjet printing of polymer solutions is an area of interest for depositing precise, high-throughput patterns of functional polymer. The applications of the polymer patterns include OLEDs, organic circuits, and textiles. Read more

Discover How BIP Technology Gases Can Release the Potential of Your GC

When it comes to GC it’s not all about gas purity, you also need a gas that eliminates the critical impurities of moisture and oxygen, which otherwise cause baseline noise and reduce peak resolution. Read more

Simplify LC Method Migration with Pro EZLC Method Translator

Pro EZLC method translation software makes it quick and easy to scale down an existing LC method to a smaller column format so you can speed up run time, increase sample throughput, and reduce solvent use. Learn more
