I found this video very interesting, with information that I could apply immediately to my work. Thank you!

The best video about using laser diffraction technique to measure and understand particle size. thanks

Congratulations Ian. That's a great presentation!!!

Thanks, it is really helpful for me to understand my data

Thanks this Video a lot! Can I tell me if measuring the partical in Liquid by Laser diffraction method, the size result is Hydrodynamic Radius or not? Thanks!

Hello sir,
I am having airborne dust concentrations data as PM10, PM2.5, PM 1 .
These data was taken before and during dust producing work in a civil construction site.
N=5
How can i compare these before and during operations data ?
It seems that there is percent variation in dust concentrations in atmosphere between before and during operation data.
e.g., PM 10 ( particle size less than 10 microns) is sharing 40% of total airborne dust, and PM 2.5 ( particle size less than 2. 5 micron) shares 10% of total airborne dust.
During machine operation:
PM 10 shares 60% and PM 2.5 10% only.
It seems that PM 10 share is increased due to that machine operation?
Which test is suitable for analysing these type similar data for discussion ?
How to use statistics?
Any comparison among these particle sizes?
thank u.

is it just me or is the sound incredibly bad? Its HORIBAL^^
