Why Graphite Furnace Atomization gives higher sensitivity over Flame Atomization

You may have all along heard that for higher detection limits you should opt for graphite furnace atomization instead of flame atomization. I presume that this was taken for granted without going into the reasoning behind the statement. The first step is to have a basic understanding of the fundamental concept of the two popular […]

Scope of ICP-MS applications

ICP-MS is acclaimed widely as the most sensitive and accurate technique for analysis of traces metals. It has an established application base in studies on pharmaceutical and food products. However, there are some other areas as well where ICP-MS has made inroads and regulatory bodies across the world have specified ICP-MS as the recommended technique […]

Understanding the response factors of a GC detector

Gas Liquid Chromatography (GLC) or simply Gas chromatography (GC)is a versatile technique that helps identify and quantify constituent compounds of complex organic mixtures. Primarily such compounds should be volatile in nature and should not decompose at high temperatures inside the injector and the column oven.  The technique offers a wide choice of detectors. For any […]

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 […]
