Currently, he works as a forensic researcher, a position that allows him to actively develop instrumental methods for the testing of illicit substances for narcotic and toxicological cases.
The conventional instrumental methods for phosphate measurement include spectrophotometry and chromatography.
However, current clinical instrumental methods for diagnostics of lung cancers (including AC), such as CT-scan, X-ray screening are still not sufficient for reliable early diagnostics of AC and prognosis of early metastasis.
Instrumental methods for measuring flavor release in the nose, such as ACPI-MS and PTR-MS, made it possible to evaluate such changes in the concentration of flavor components at low sensitivity and high selectivity in real time.
The purpose of analyzing this set of extracts was not to characterize or compare previously reported values of NIST SRM material as previously described [ 17], but to demonstrate the applicability of our two independent instrumental methods for environmental samples, and to compare values between the LC and GC generated data.
It was clear over 30 years ago that gas chromatography mass spectrometry (GC MS) was the instrumental method of choice for dioxin and furan determinations.
Polarography is an instrumental method of chemical analysis used for qualitative and quantitative determinations of reducible or oxidizable substances.
A variety of extraction and cleanup methods have been reported [ 6, 9, 14– 16], but for the purpose of this paper, we will focus on instrumental methods of analysis for PBDE congeners.
The nondestructive instrumental methods are for instance exceptionally quick and involve very little sample preparation, but expensive and sophisticated equipment is required which might not be widely available.
The precision of the instrumental method was assessed by performing DIs of the same sample for As V).
