Researchers are surrounded by dangerous elements, from infectious microbes to cranky advisors. With hazards all around, it’s easy to forget how deadly even common lab chemicals are. But don’t worry…
Continuing our discussion on modern extraction techniques for Pesticides residue analysis, we will be looking now at Solid Phase Microextraction (SPME) and Microwave Assisted Extraction (MAE) techniques. 3. Solid…
Figure 1 : Noise in the Laboratory Noise and dust are completely different in most respects, but they share one common property; they propagate through the air. This means that…
Due to intensive use of pesticides, their residues have become an unavoidable part of the environment, and they are often detected in all environmental segments and therefore their monitoring has…
Anyone who’s studied chemistry will be overly familiar with titrations. It’s an analytical technique that can be used to find the concentration of a solution (the amount of a solute dissolved…
Safer working conditions have a way of developing over time as we become more knowledgeable. Remember this famous photograph from the 1930s of ironworkers eating lunch? No hardhats. No fall protection systems.…
Exposure to noise in the laboratory can lead to irreversible hearing damage. According to the HSE, around 20,000 working people in the UK suffer from Noise Induced Hearing Loss (NIHL) that…
Are you a laboratory owner? So what is the core benefit you want when you are running a lab business? Isn’t the answer ‘money’? Revenue and Profits are the core…
