A “good” calibration set should show:

The MP-AES requires flammable gases for plasma operation.

What can be said about a spectrum for acetic acid if a peak is found in the range of 1650-1580? (i.e. the compound is identified to be acetic acid but there is a peak in this range)

Why is it necessary to use a calibration curve in MP-AES analysis?

In the FT-IR spectrum, the peak for the C=O stretch of an aldehyde or ketone typically appears around __________ cm⁻¹.

When preparing nitric acid solutions, you should always add acid to water, not the reverse.

When using a nitrogen generator, a purge time up to ____ minutes may be needed to reach required nitrogen purity.

A sharp feature near ~2350 cm^-1 often indicates ________ interference from the atmosphere.

What might be the cause if unusually high background levels are observed across the spectrum?

Match the number with the part it identifies on the MP-AES:
