Deep-UV Laser Ablation Technology Coupled with Plasma Quadrupole Mass Spectrometry for Rapid Determination of Nickel

Knowledge of nickel/vanadium (Ni/V) ratios in petroleum fuel is essential to source geochemical information and to limit catalytic poisoning and corrosive effects in chemical refining processes.

However, these ratios have been found to vary widely and are affected by various factors, including the sulphur content of the petroleum feedstock. They are normally obtained by digesting and treating the feedstock in suitable acid or organic media followed by numerical analysis.

Our research investigated a novel sample introduction technique for obtaining Ni/V ratios by ablating petrified asphaltene samples (following liquid nitrogen pre-treatment) with a 213 nm laser beam coupled to a hyphenated plasma mass spectroscopic system.

Investigation of Isotopic Abundance Ratio of Biofield Treated Phenol Derivatives Using Gas Chromatography-Mass Spectrometry

Butylatedhydroxytoluene (BHT) and 4-methoxyphenol (4-MP) are phenol derivatives that are generally known for their antioxidant properties and depigmenting activities.

The aim of this study was to evaluate the impact of biofield energy treatment on the isotopic abundance of BHT and 4-MP using gas chromatography-mass spectrometry (GC-MS).

BHT and 4-MP samples were divided into two parts: control and treated. The control group remained untreated while the treated group was subjected to Mr. Trivedi’s biofield treatment.

Development of a Method for Regioisomer Impurity Detection and Quantitation within the Raw Material 3-Chloro-5-Fluorophenol by Gas Chromatography

Impurities within the raw materials used to prepare active pharmaceutical ingredient (API) are a severe cause for concern.

The entire challenge lies in the quantification and detection of regioisomer impurities.

Impurities should be indentified at the earliest and gas chromatography area% method can be used for the detection and quantization of impurities like 3-chloro-5-fluorophenol.
