Analyte
- Liquid and solid samples
- Small, polar, ionic and thermally labile molecules as well as high molecular weight biopolymers
- Assumption:
- Ionizable molecules - molecules with heteroatoms
- Soluble in suitable solvents
Equipment
- API 2000 Tripel-Quadrupol-mass spectrometer, Applied Biosystems/Sciex Co.
Operating method
- Stand-alone: integrated injection pump - continuous sample feeding
- Coupling with HPLC: flow-injection (without HPLC-column) and with former separation (HPLC, IC, GPC)
- Mass range 5 - 1800 m/z
Characteristic features
- Analytes are dissolved in solvents or solvent mixtures
- Soft ionization by spray technique
- Result: quasi-molecular ions as well as fragments
- High selectivity and detection sensitivity
- Quantitative analysis of the analytes possible, calibration necessary
- MS/MS delivers structural information
Applications
- Investigation of hydrolyzed starch- and cellulose derivates
- Identification and quantification of extractable polymer additive
