Derived from the laboratory burette method (titration method), the Lovibond drop test range is an established methodology used across the water industry forming an integral part of the analytical program of many a speciality chemical supplier.
In the drop test method like in the laboratory titration technique, a solution of known concentration is used to determine the concentra...
The FOS/TAC ratio is a commonly used indicator for assessing the fermentation process within biogas reactors, where FOS is a measure of the volatile organic acids (measured in mg CH3COOH/l) and is TAC is a measure of the total inorganic carbon i.e. the alkaline buffer capacity of the system (measured in mg CaCO3/l). In simple terms, this ratio looks at acid vs alkaline in the system which helps...
Sulphur dioxide ( SO2) is used in food and drinks for it's preserving and anti-oxidising properties. It was used back by the Romans in wine making, when they found that burning sulphur candles inside the empty wine vessels kept them fresh and free from the vinegar smell. Nowadays Sulphur dioxide is used to preserve the colour, flavour and stability of the wine. As an antimicrobial SO2 interf...

Why is alkalinity an important parameter in environmental water analysis?
Its not just pH
[caption id="attachment_6437" align="aligncenter" width="300"] Vials[/caption]
Answer:Â Alkalinity is a measure of the acid-neutralizing or buffering capacity of a solution. The properties of water are is easily influenced by alkalinity, making it an important and widely used test. If any changes are mad...
Total Acid Number (TAN):
[caption id="attachment_5085" align="aligncenter" width="300"] Oil testing[/caption]
Total Acid Number (TAN) is a measure of the quantity of acidic compounds present in a petrochemical sample. The TAN value is determined for both new and used oil samples. New oils are monitored to ensure the initial quality of the oil meets the specific TAN range for the sample type. U...
Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
