General description
Application
Also reported for use as a component of extraction mixture in screening drugs of abuse in urine samples by GC-MS.
Features and Benefits
- suitability tested and specified for UHPLC-MS and UHPLC-UV: for analytical flexibility
- specified quality in positive and negative electrospray ionization (ESI) and atmospheric-pressure chemical ionization-mass spectrometry (APCI-MS) for lowest detection limits and confidence in analyses in all important MS modes (test 1)
—ESI/APCI (-) < 10 ppb
- lowest impurity profile: for interference-free baselines (test 2)
- microfiltered through 0.2 μm filter (test 3) to provide:
—reduced risk of column clogging
- packaged in borosilicate glass bottles for minimized contamination with metal ions
- lowest levels of trace metal impurities to minimize metal ion adduct formation
- lowest level of polyethylene glycol (PEG) impurities in UHPLC-MS solvent lineup (PEG S/N signal-to-noise-ratio < 50)

HPTLC separation followed by UV detection of the bitter acid content in various hop samples.
Protocols
HPTLC was used to analyze caffeine in coffee. Filtration of coffee through a PTFE syringe filter was the only sample preparation. Quantitation was conducted with a TLC scanner.
Thin layer chromatography coupled with mass spectrometry does not require substantial sample preparation. Energy drinks can be applied without dilution directly onto the TLC plate.
HPTLC–MS analysis of quinine in tonic water and caffeine in coffee and cola drinks. Tonic and cola drinks decarbonized through ultrasonication, and coffee extracted through PTFE filter.
The modern thin-layer chromatography (TLC) offers advantages also in the field of cosmetics to quickly and simultaneously analyze samples with densitometric detection.
