Special Note: This is the first Quiz included with our newsletter. For each issue, we’ll choose a chromatogram from a different application or industry. So if Carbamates don’t apply to your lab this round, stay tuned!
Simply email your answer and your full contact information by December 1st to: Rebecca at firstname.lastname@example.org
The troubleshooting answer and winner congratulations will be published in the next issue.
