UTLC-Desorption Electrospray Ionization-Mass Spectrometry AND UTLC-Direct Analysis in Real-Time Mass Spectrometry... 

Silicon nitride coated CNT-templated UTLC plates were employed for analyte detection via DESI-MSI and direct analysis in real-time mass spectrometry (DART-MS) after chromatography. Rhodamine B (m/z 443.2 M+) and Basic Blue 7 (m/z 478.3 M ) were desorbed with methanol as spray solvent at 0.003 mL min within 45 min for scanning an 85-mm plate section (Figure 9.9). Dimethyl Yellow (m/z 226 [M-i-H]+), Oracet Red G (m/z 238 [M-i-H]+), Solvent Blue 35 (m/z 351 [M-t-H]+), Sudan Red G (m/z 279 [M-i-H]+), and Solvent Blue 22 (m/z 305 [M-i-H]+) were detected within 3.5 min with a snbstantially optimized interface for HPTLC-DART-MS applying a helium flow of 3 L min at 500°C (Figure 9.10) [2].

Other ambient mass sp>ectrometric ap>proaches, such as low temperature plasma mass spectrometry (LTP/MS) and direct analysis in real time mass spectrometry (DART/MS), have been used to characterize less polar components in olive oil samples. The use of organic solvents and/ or additional reagents in the source is unnecessary, except for the use of helium gas for discharging (Garcia-Reyes et al., 2009 Vadavik et al, 2009). The results indicate that both techniques are potentially useful for characterizing polar components in petroleomics applications.

A rapid screening method by means of direct analysis in real time mass spectrometry, DART-MS, using a single-quadrupole mass spectrometer, was developed. A plastisol sample was introdueed into the DART interfaee, protonated moleeules and ammonium adduets were obtained. Additives present in the 1% range eould be direedy and easily identified. ...
