The HyperFlux™ PRO Plus analyzer provides high-quality measurements in real time

Leave a Comment / Analysers / By

The team at Tornado Spectral Systems recently ran a simple experiment to show how their HyperFlux™ PRO Plus analyzer provides high-quality chemical concentration measurements in real time. They added small quantities of propylene glycol (PG) to pure water while collecting spectral data every 2 seconds. Traditional spectrometers would have to run about 10x to 30x …

Real Time average particulate matter concentrations in Belgium

News & Announcements / By

Current 24-hour average particulate matter concentrations of less than 10 micrometres (μm) in Belgium The smaller the particulate matter, the deeper it can get through the airways in the human body. The smallest particles can penetrate into the blood. PM10 can disrupt the mucous membrane in the airways, cause respiratory complaints and increase sensitivity to …

Particulate matter is fatal for the elderly after one day

News & Announcements / By

Fine dust now appears to be deadly in the very short term, American researchers discovered. Many people over 65 die one day after being exposed to particulate matter. Researchers at Harvard University put the death date of 22 million American over-65s (in the period 2000-2012) in addition to the particulate matter data in that period. …
