Selecting a suitable detector for Gas Chromatographic analysis

Gas Chromatography offers a wide range of detectors to meet your analysis applications. The two detectors which are in common use are the Flame Ionisation detector and Thermal Conductivity detector as these cover detection of majority of compounds encountered in routine applications. However, there are other detectors also available which are useful for specific applications. […]

Comparative evaluation of sample digestion techniques for Atomic Absorption Spectroscopy

Trace metals analysis by Atomic Absorption Spectroscopy requires the introduction of the sample into the system as a homogeneous liquid. It is necessary to digest solids for complete extraction of analyte(s) of interest into the solution. Commonly used practices are: Acid digestion Fusion Ashing The technique adopted should be safe, reproducible and afford to save […]

Simple Tips to improve reliability of pH measurements

pH plays a crucial role over control of course of chemical and biochemical reactions and therefore finds widespread use in laboratories and manufacturing industries. Slightest variations in pH can result in erroneous results of reactions or yields in manufacturing operations. A pH meter is a delicate device and should be handled with care. Additionally, some […]

Guidelines on Preservation of Sample Integrity prior to analysis

Sampling plays a crucial role and deserves the same degree of attention as final analysis. Unfortunately, more than often the responsibility for sample collection and packing for despatch is entrusted to untrained persons and this can contribute to the poor reliability of results for which the analyst gets blamed though he is not at fault. […]

Special considerations in analysis of critical laboratory samples

Referal laboratories play a significant role in all countries as they are considered to be authoritative and results communicated by them are accepted without questioning. Such laboratories analyze hundreds of samples daily. Analysis of each and every sample is important but at times critical samples are required to be analyzed. Such samples are often received […]

The Essence of a Laboratory Notebook

Through college, most of us have come to make utility of paper planners to manage days. One can capably take down due dates, phone numbers, scribble, and make to-do-lists on the go with just a pen and paper at hand. In the laboratory, paper planners are particularly useful because one can organize so many things […]

Suggestions on use, qualification, handling and storage of laboratory working standards

Laboratory analysis is authentic only when there are standards for comparison of results obtained with the results obtained with standards under an identical set of experimental conditions. However, practically it is not possible to make use of original reference standard every time analysis is carried out as the quantity available is small due to its […]

The uses of a Faraday cage – an electrochemist’s point of view

The Faraday cage represents a shelter that can be built using various materials – wood, plastic, brick (non-conducting materials). The exterior of this cage should contain conductive materials such as aluminum, iron, copper or galvanized wiring. The outer coating of a Faraday cage should be perfectly closed from one end to another and conductive on […]

Suggestions for improvement of laboratory workflows

The productivity of a laboratory can be improved consistently through judicious utilization of resources, the timely addition of resources and effective use of manpower.A clear vision of future goals will be helpful in planning for the set goals. The article is an attempt to offer some useful suggestions for achieving a sustained growth in workflows. […]

Importance of using contamination free laboratory glassware

Contamination is a serious issue in laboratories and often results in unpredicted errors in analysis results. All laboratories should adhere to preventive measures to overcome errors due to sample contamination. Contamination from external sources or contact with other samples and sampling tools are considered to be the main sources of contamination and cleanliness of glassware […]
