“…Although GC-APCI was introduced more than three decades ago by Horning, the general acceptance of GC-APCI-MS is certainly constrained by the lack of spectral libraries [101], which make the traditional GC-MS approaches so powerful. Database of APCI are recently available [93,101] and the accurate mass of the molecular ion is the main feature of these API-based libraries.…”

“…Gas chromatography mass spectrometry (GC-MS) is usually performed with electron impact (EI) and chemical ionization (CI) at reduced pressure [3]. For ionization at atmospheric pressure following the separation of compounds via GC, APCI is used [4]. Atmospheric pressure laser ionization (APLI) is superior to all of these techniques as regards sensitivity.…”

New derivatization strategies for the ultrasensitive analysis of non-aromatic analytes with APLI-TOF-MS

Atmospheric pressure laser ionization (APLI) (Constapel et al. in Rapid Commun Mass Spectrom 19:326-336, 2005; Schiewek et al. in Anal Chem 79:4135-4140, 2007; Schmitz and Benter (2007) J Chromatography Library 72:89-114) is an ultra-sensitive and selective ionization method for the determination of polycyclic aromatic compounds. The selectivity is an advantage but also a disadvantage. To overcome the limitation of APLI to aromatic compounds, we have already reported some derivatization strategies for common organic functional groups (Schiewek et al. in Angew Chem Int Ed 47:9989-9992, 2008). Here, we describe the synthesis of new APLI ionization labels and their use in new derivatization strategies. These new labels widen the range of APLI-(TOF)MS analysis to non-aromatic compounds with the most common functional groups such as amines, alcohols and carboxylic acids to gas chromatography (GC) and lower the limits of detection (LOD) down to concentrations as small as pmol/L and attomole on column.

The present paper provides a brief overview of the most recent techniques for microalgae lipid analysis such as high performance liquid chromatography (HPLC), gas chromatography (GC), mass spectrometry (MS) and nuclear magnetic resonance (NMR). The application of HPLC technique is to break down lipid into smaller fractions such as neutral lipid and polar lipid. MS technique is known as less sensitive than GC technique thus requires coupling with other techniques in order to analyze the microalgae lipid. On the other hand, NMR technique provides comprehensive information on the molecular structure of microalgae lipid but it has disadvantage as the signals may overlap in the spectrum. Notably, GC coupled with flame ionization detector (FID) is the fundamental method which is fast with high accuracy when analyzing microalgae lipid.
