Curie point pyrolysis mass spectrometry has also been valuable in providing information about the chemical types that are evolved during the thermal decomposition of coal (Tromp et al., 1988) and, by inference, about the nature of the potential chemical types in coal. However, absolute quantification of the product mixtures is not possible, due to the small sample size, but the composition of the pyrolysis, product mix can give valuable information about the metamorphosis of the coal precursors and on the development of the molecular structure of coal during maturation. However, as with any pyrolysis, it is very important to recognize the nature and effect that any secondary reactions have on the nature of the volatile fragments, not only individually but also collectively.

In a later paper, De Haan et al. (1981b) report on the seasonal variation in the composition of fulvic acids determined by Curie point pyrolysis-mass spectrometry. Water samples were collected monthly between January and September, 1978, and fulvic acid fractions were isolated by gel permeation chromatography. Differences in the chemical composition (particularly striking in the pyrograms of fractions of high apparent molecular weight)...

Seven Argonne Premium coal samples ranging from lignite to low volatile bituminous in rank were analyzed by Pyrolysis-Field Ionization Mass Spectrometry (Py-FIMS) in order to determine the existence and structural nature of a thermally extractable "mobile phase". In addition, Curie-point Pyrolysis-Low Voltage Mass Spectrometry (Py-LVMS) was employed to demonstrate the importance of mild oxidation on the thermally extractable mobile phase components.

In pyrolysis-mass spectrometry (Py-MS) the pyrolysate is directly transferred to a mass spectrometer and analyzed, generating a complex spectrum. The sample introduction can be done using various techniques. One simple technique is the direct insertion probe (DIP) where the sample is deposited on an insert that has the capability of heating the sample and of introducing the pyrolysate directly into the ion source of the mass spectrometer (see e.g. [1]). Another technique is the Curie point Py-MS where an attachment to the mass spectrometer allows the sample to be placed in a radio frequency (RF) region continued by an expansion chamber connected to the ion source. The sample is pyrolyzed and the pyrolysate ionized and analyzed in the MS instrument. A schematic diagram of a Curie point Py-MS system is shown in Figure 3.3.2. 

Curie-point Pyrolysis-Gas Chromatography/Mass Spectrometry (Py-GC/MS). 

Natural black (human hair, bovine eyes) and synthetic (tyrosine, dopa, and dopamine) melanins were investigated by Curie point pyrolysis-gas chromatography-mass spectrometry (86,96). The pigments were characterized by different ratios of degradation products identified as aromatic hydrocarbons, phenols, catechols, pyrroles, and indoles. The amount of ash in karakul lamb wool was correlated to its color, with black producing the most (3.9%) and white the least (1.2%). Similar studies showed a correlation with the calcium content (317,318).
