All articles from Lab Training, covering chromatography, spectroscopy, microbiology, and analytical method validation, in order of publication.
IR spectroscopy is a popular qualitative identification technique which uses comparison of the spectra of unknown sample with the spectra of known standard materials. Such spectra can be manually overlaid for peak to peak comparisons
UV – VIS Spectroscopy exploits the absorption of light in the UV and visible regions of the electromagnetic spectrum by chemical absorbing species.
You shall be pleased to know that the Certificate course on Atomic Absorption Spectroscopy is launched.
Interlaboratory comparisons serve the purpose of validating the capability of your laboratory to provide accurate and reliable results within permissible levels of uncertainty to your customers and also to ensure that the adopted analytical method is suitable for the intended purpose.
Classical analysis techniques are easily understood and adapted by all those having an understanding of basic concepts of chemistry and analysis.
Titrimetric analysis or volumetric analysis offers distinct advantages over cumbersome gravimetric methods
Analysis results are authentic only if the samples taken for analysis are representative of the whole. A sample represents a bulk quantity such as sea water, river, lake water, rock from a mining site, tissue or body fluid from a living being, raw material consignment or finished product representing a manufactured product.
Calibration of laboratory instruments is an essential activity which gives confidence on reliability of your results. Both determinate and indeterminate errors contribute to variations in your results.
Certified reference materials are indispensable for validating the results of analysis. Like any other laboratory reagents they involve a recurring cost but their costs are higher than regular reagents.
Each section refers to a specific regulated area. 21 CFR refers to Pharmaceutical and Medical devices and Part 11 reference to electronic records and electronic signatures.
One can control deviations form laboratory test procedures by permitting only authorized changes. Standard test procedures are sacrosanct documents
All laboratory workers require professional skills in order to carry out laboratory operations. Skill development and acquisition of knowledge promise career growth through better understanding of the job requirements.
Quality Assurance and Quality Control are often used synonymously as the differences between them are not clear to most of us.
Laboratory’s have much higher energy consumption requirements compared to commercial organizations of similar size.
Laboratory safety is of prime concern for all laboratory workers as a laboratory presents a multitude of hazards due to presence of potentially dangerous materials.
Trace metal analysis is referred to as analysis of elements in different matrices at levels below one ppm. The article Which technique should I use for trace metal analysis is a refresher on the common techniques used for trace metal analysis.
A modern analytical laboratory handles several hundred samples in a single day. Sample management plays a crucial role as without a sample management plan in place it will not be long before the laboratory presents a chaotic look with samples lying all around.
Your analytical results should be consistent if you adhere to the specified method and take all the prescribed experimental precautions
Interview Questions for a Microbiologist. Find Microbiology interview questions and answers with explanation for interview, competitive examination.
As already discussed in the earlier article Contributions of Microbiology in Food Industry, they are used in production of various food products, and are also responsible for food spoilage thereby causing intoxication and diseases
The dividing line between instrumental and non-instrumental methods is very fine. Check out the distinct benefits of Modern Analytical Instrumental methods.
The Contribution of microbiology to the pharmaceutical industry is the development of antibiotics. In addition, microbiology contributes towards quality control of a pharmaceutical laboratory.
Food Microbiology covers studies on Food spoilage by different kinds of microorganisms such as bacteria and fungi, Testing of Food/ food products for microbial contamination etc.
A set of suggestions were provided on storage of laboratory chemicals. Chemicals having similar characteristics such as flammables, acids, bases, corrosives, oxidizing agents and toxics, with some exceptions, can be stored together in a planned sequence.
