What is the smallest mass that I can weigh?
Have you ever tried to ponder on what is the smallest mass that can be weigh.You may come up with figures in the range of microgram(10-6g), nanogram(10-9g) or at best picogram(10-12g).
General applications of HPLC based on solute – stationary phase interaction classification
HPLC has been classified into four categories based on interactions between solutes in the mobile phase and the stationary phase.
Concentration Calculations in Analysis
Most of us were exposed to chemical calculations in school and college days. As we pursued higher degrees and progressed in our career as analytical scientists we took more interest in learning new techniques and picking up operational details of analytical instruments.
Advances in HPLC Stationary Phases in Monolithic HPLC columns
Stationary phases for HPLC have evolved from irregular particles to spherical particles to sub- 2μm size particles and core shell technologies. Parallel advances have been seen in development of monolithic packings

Over the years HPLC has acquired a top position in both academic and industrial laboratories.
Role of Buffers in Reverse Phase HPLC Separations
Reverse phase separations of polar and ionizable compounds requires precise control of pH using buffers in Reverse Phase HPLC Separations
Why is Degassing of HPLC Mobile Phase Necessary ?
Bubble formation on mixing of solvents can lead to a number of problems which can be prevented by degassing of mobile phase.
Importance of Sample Filtration in Liquid Chromatographic Analysis
Sample filtration plays a major role in analytical chemistry. Read more about the importance of sample filtration in liquid chromatographic analysis.
Chromatographic Syringes
A Chromatographic Syringes is a high precision liquid measurement and transfer device capable of maintaining its designed performance
Correct Handling and Care of pH meter
A laboratory may not be equipped with sophisticated instruments such as AAS, GC, HPLC, LC – MS or FT – IR but it simply cannot do without a pH meter as pH measurement is a basic requirement for all chemical and biochemical reactions and process control reactions in manufacturing industries.
calibration curve and calculate sample concentrations
This is a video tutorial for using Excel to create a calibration curve using six standards and using it to automatically back calculate unknown sample concentrations.
Introduction to Analytical Method Validation
Learn the basics of analytical method validation, its importance, why it is needed, what all parameters are to be covered as part of validation and their definitions.
Osmometry in the Pharmaceutical Industry
For accuracy in the preparation and labelling of parenteral solutions osmolality should be measured carefully with the vapour pressure or freezing point based osmometer rather than being calculated based on the concentrations of ingredients added.
