Instrumental methods are now becoming accepted as alternative techniques, provided they are shown to give equivalent results to the conventional test. These methods can allow a greater throughput of samples, with less operator dependence than conventional techniques, and often generate useful data that were not previously available. In fact, there are some instrumental companies, i.e., LECO Corporation, devoted almost exclusively to the development and sale of apparatus for chemical analysis - immediate analysis, elemental analysis, sulfur determination -calorific value, ash fusibility, and other technical tests of coals.

Chemical analyses. The C and H analyses were done on a Carbon, Hydrogen, Nitrogen Analyzer CHN-600 (Leco Corporation). Samples were weighted in dry nitrogen atmosphere into small copper samples holders. The samples were burned in oxygen atmosphere at 950 C, and hydrogen was detected as H2O using an IR cell and carbon as C02 by another IR cell.

The Fiehn Library is a mass spectral and retention index library for comprehensive metabolic profiling. The library comprises over 1000 identified metabohtes that are currently screened by the Fiehn laboratory. The compound list is continually extended. The Fiehn mass spectral library is commercially available for GC-quadrupole mass spectrometers from Agilent Technologies, and for GC-TOF mass spectrometers from Leco Corporation, see http //fiehnlab.ucdavis.edu/Metabolite-Library-2007/...
