Archaeometric analysis Chromatographic analysis and structural determination Pottery. Content analysis

Gass Chromatography-Mass Spectrometry Pottery. Lipids analysis Destructive method for the identification of the total lipid profile: fatty acids, sterols, wax esters, fatty alcohols, triacylglycerols, etc. Any remains of soil were removed with an electric hand-drill. The sample was then grinded to the appropriate size in an agatha mortar (0.25 mm). Extraction with a the mixture chloroform/methanol (CHCl3:MeOH) (2:1 v/v) assisted by ultrasound. Derivatization of lipids to trimethylsilyl derivatives (TMS). The reaction tales place at 70 ºC for 30 min using N,O-bis-(trimethylsilyl) trifluoroacetamide (BSTFA) with 1 % trimethylchlorosilane (TMCS). The sample is solved in cyclohexane and then injected in GC-MS. Chromatographic separation is performed applying an adequate temperature programme. Gas chromatography-Mass Spectrometry (GC-MS) The analyses were performed using a using a gas chromatography equipment (model Thermo TraceGC Ultra) coupled to a Thermo DC Q II mass spectrometer. Autosampler Thermo Triplus (CICT, University of Jaén). The samples were introduced by on-column injection into a 15 m x 0.25 mm I.D. fused silica capillary column, coated with poly(dimethylsiloxane) stationary phase with 0.1 μm film thickness. Helium was used as the carrier gas (purity 99.99%). | |
High Performance Liquid Chromatography-Mass Spectrometry Pottery. Analysis of triacylglycerols Destructive method for the identification of TAGs content. Any remains of soil were removed with an electric hand-drill. The sample was then grinded to the appropriate size in an agatha mortar (0.25 mm). Extraction with a the mixture chloroform/methanol (CHCl3:MeOH) (2:1 v/v) assisted by ultrasound. Derivatization is no needed. Lipid extract is solved in isopropanol and then injected in HPLC-APCI-MS. Chromatographic separation is performed applying an adequate mobile phase gradient (mixture of isopropanol and methanol). High Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) Agilent 1290 Infinity HPLC system connected to an Agilent 6220 TOF (time-of-flight) mass spectrometer equipped with APCI (Atmospheric Pressure Chemical Ionization) interface. (Departement of Physical and Analytical Chemistry, University of Jaén). Chromatographic column Zorbax Eclipse Plus C18 (150 mm x 4.6 mm, 1.8 μm particle size). |
