Levels of airborne particulate pollution is measured as a means of monitoring air quality. Airborne particulates (PM) can be solid particles or liquid droplets. They come in different sizes, compositions and origins (i.e. natural or synthetic). This means they can all have differing effects on human health. PM2.5 and PM10 are two standard particle sizes that are monitored:
Coarse particles...
Silt Density Index (SDI) is a test used to determine the levels of colloidal and particulate suspended solids in the feedwater to reverse osmosis (RO) systems. This in turn will enable you to estimate the fouling potential. This measurement is of importance as it can be used to predict the lifetime of the RO membrane. This can help save time and money. It is measured following the test...
Suspended solids tests are conducted as a water purity indicator, and to form part of discharge consent. The gravimetric method of suspended solids testing requires filter papers to be used, but these must be of the correct grade to ensure correct results.
We've taken a look at which filter paper grades are approved for suspended solids tests.
Which filter paper should I 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...
