Modern gas flow monitoring practices: a review of ULSTR-sonic systems within CEMS applications
1. Introduction Originally TA LUFT and later USA EPA regulations required emissions reporting on a daily mass basis. This stimulated the development of continuous flow monitors to allow accurate determination of mass emissions. At present in the UK, annual tonnages for particulates, SO2 and NOx are calculated using a factor for m³ flue gas per kg fuel burned. It is envisaged that future EC ...

Improve fed-batch fermentation by measuring mass flow
How can my fermentation process yield a more consistent product? Any biochemical process is only as consistent as the parameters that control it. What makes a fed-batch fermentation process particularly susceptible to variation is the fact that it relies on many critical parameters. With an aerobic fermentation process, temperature, pO2, substrate consumption, and pH are primary critical ...

Using a Gas Liquid Porometer to Reliably Measure Pore Size and Distribution for Filter Media Used in Face Masks
Surgical masks and respirators are typically made of nonwoven polypropylene fabric and mostly consist of three (or more) layers. The first and third layers are generally spunbond, while the middle layer is meltblown. This composition is commonly referred to as SMS technology (Spunbond/Meltblown/Spunbond). Three layers of respirator fabric While the efficiency of face masks is measured by ...
