From Beynon table, one can predict the possible elemental arrangement or composition of particular mass and determine the molecular formula of compound. Similarly, a method was developed for determining common drugs of abuse in body fluids using liquid chromatography-atmospheric pressure chemical ionization mass spectrometry (LC-APCI-MS). The sample for forensics in the case of drug abuse is mainly urine, hair and blood. Steps for determination of hydrogen deficiency index: Make the correction in the predicted base formula with respect to the elements obtained from other spectral data, and the correction requires addition or removal of hydrogen atoms, which depends upon the type of element added. There are some rules which are employed in interpretation of mass spectra in structure elucidation process. It is divided into two parts: If m/e value of molecular ion peak is odd number, then it may contain odd number of nitrogen atoms. It is also used as a sensitive detector for chromatographic techniques like LC–MS, GC–MS and LC/MS/MS. Analysis of methadone and its metabolites with other illicit drugs like cocaine, phencyclidine, heroin and 6-acetylmorphine in hair by GC–MS is another successful application of mass spectroscopy .
In both cases analytical runtimes are typically in the order of less than 10 minutes per sample and can accommodate large batches of samples to achieve quantitative analysis using daily calibration curves, quality control samples and unknowns. Hence, the evaluation of bile acid can become useful for investigating the liver or intestinal functions along with the diagnosis of various diseases such as cholestasis, colon and liver cancer. Any substance with hydrogen deficiency index four or more possibly contains a benzenoid ring in it, and the compounds with hydrogen deficiency index less than four cannot contain such type of ring. Triple Quadrupole Mass Spectrometry Mass spectrometers are often identified by the type of mass analyzer employed in the selective transmission of ions within the instrument. It has 100% abundance. The Mass Spectrometry and Proteomics Facility provides academic and industry researchers access to specialist mass spectrometry and proteomic equipment and expertise. Then, the signal is transferred to a data collection system for data investigation. By optimization, the cost of operation reduces to one-tenth that of conventional method with automated biochemical testing platforms. Within the Core MS Facility, sophisticated instruments are housed for the analysis of compounds ranging from small organic molecules up to large proteins. These are often used as characteristic of a compound for identification. The mass spectrometry imaging (MSI) suite offers the choice of DESI or MALDI methods for the detection and high-resolution visualisation of biomolecules in samples ranging from tissue sections to bacterial colonies.
