FTIR spectra are unique to each compound and can serve as molecular fingerprints.

The FTIR baseline drift in a humid lab is most likely due to:

The internal standard (Tridecane) helps correct for injection volume variations and instrument response fluctuations.

When switching from a volatile to viscous oil, one must:

The presence of aromatic overtones near 2000–1600 cm⁻¹ confirms:

List the two types of results that can be provided through FTIR? [1] [2]

If your method blank is 0.30 ppm Ca, the most defensible correction is to:

Your residuals are: low (+), mid (+), high (+) all positive. Best interpretation?

Unknown concentrations (µg/mL) from three injections are 647.4, 641.5, 652.9. Compute mean, SD, and %RSD. Mean = [A] (Report to 1 decimal place) SD = [s] (Report to 1 decimal place) %RSD = [RSD] (Report to 2 decimal place)

The calibration curve is created by plotting the ___________ against the known concentrations of Dodecane.
