I just hope they give the option of asynchronous (recorded) lectures (so no iClickers). Was it this way last semester? Mass spectrometry (MS), i.e. the gas-phase measurement of compounds’ mass-to-charge (m/z) ratio, is a key approach for identifying and quantifying chemical compounds. Biomolecules (even large proteins) can enter the gas phase by using soft ionization techniques such as electrospray ionization (ESI) or atmospheric chemical ionization (APCI).likely to take Chemistry 130 against advising, even when the engineering students were removed from the set.
