25-25. Chromatography-mass spectrometry. Cocaine metabolism in rats can be studied by injecting the drug and periodically withdrawing blood to measure levels of metabolites by HPLC-mass spectrometry. For quantitative analysis, isotopically labeled internal standards are mixed with the blood sample. Blood was analyzed by reversed-phase chro- matography with an acidic eluent and atmospheric pressure chemical ionization mass spectrometry for detection. The mass spectrum of the collisionally activated dissociation products from the m/z 304 positive ion is shown in the figure on...

Electrospray time‑of‑flight (TOF) mass spectrometry was used to analyze the eluate from a high‑performance liquid chromatography (HPLC) separation. The mass spectrum of one chromatographic peak, containing a protein of unknown molecular mass, displays MHnn+ peaks at m/z= 6636.908, 6194.524, 5807.480, 5465.932, 5162.360, and 4890.726. Find the average molecular mass (M) of the neutral protein and its standard deviation.

High performance liquid chromatography (HPLC) deals with liquid samples at high pressures whereas mass spectrometer (MS) operates at normal temperatures and requires high vacuum conditions. Describe in detail hovw these very conflicting conditions are taken care of in the process of combining the two techniques resulting in a hybrid technique known as HPLC-MS. Use...
