Hazardous Laboratory Spills
Hazardous Laboratory Spills can happen in all laboratories irrespective of their size or sophistication.
Why is Conditioning necessary for GC Columns?
Conditioning is a process involving flow of carrier gas through a GC column at elevated temperature to flush out residual contaminants and make it fit for reliable use.
Four Key Considerations for choice of Capillary Gas Chromatography Columns
Choice of Gas Chromatography column internal diameter depends on the concentration of the sample. When sample loading exceeds Gas Chromatography column capacity there is loss of resolution, poor reproducibility and peak distortion.
Common Peak Shape Distortions in HPLC and their Prevention
A chromatographer always looks forward to getting perfect shaped peaks for each and every analysis but in reality peaks get distorted due to numerous reasons.
Familiarize Yourself with Laboratory Safety Devices and Symbols
In the earlier article General Guidelines for Laboratory Safety you were provided tips on safe practices for carrying out different laboratory operations and processes. It is equally important to familiarize with safety symbols that you are likely to come across on laboratory walls, solvent and reagent bottles,containers and instruments in the laboratory.

Analytical Procedure Errors and their Minimization
An understanding of analytical errors is essential before you report your results with the required level of confidence. However, before talking about errors you should have clarity on the terms accuracy and precision. Most of us believe that these terms have same meaning but the example of arrows striking a target.
Insight into Journals on Analytical Science and Research
Analytical chemistry has entered into all spheres of human activities ranging from studies of natural resources, man-made materials, environmental monitoring, medical diagnosis and health monitoring, crime investigations, studies on archaeological artifacts to oceanographic and marine studies.
General Guidelines for Laboratory Safety
While it is not possible to cover the entire subject on the laboratory safety in a short article such as this one an attempt is made to provide some useful guidelines when carrying out different laboratory operations and processes.
Measurement Units Commonly Used in Analytical Work
As an analytical scientist your main concern would have been to report your findings in terms of what is present in your sample and in what amount. Most instruments convert input in other units to concentration or other required units. ou might be inclined to think that it is sufficient to have a knowledge of concentration units and their interconversions
Advantages and Disadvantages of different HPLC Pump Configurations
A brief introduction to different types of HPLC pumps was provided in module 7 of our free course on HPLC.
Advances in HPLC Stationary phases in Zirconia HPLC columns
Silica-based HPLC columns have remained workhorses in HPLC laboratories. Over the years with advances in particle technologies size reduction has been possible from 5μm to sub- 2μm which led to development of UHPLC.
