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 […]

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 […]
