Malvern Data:

1)  Date (dd/mm/yyyy)     - this is the date of the test run.

2)  Time (sec)            - this is the time in seconds since start of each individual run.

3)  Trans(Value)          - this is the Transmission % for the flow.

4)  Dv(10)(Value)	  - this is the 10th percentile of the cumulative volume distribution. It is the size below which there is 10% of the volume of the sample.

5)  Dv(50)(Value)	  - this is the maximum particle diameter below which 50% of the sample volume exists - also known as the median particle size by volume.

6)  Dv(90)(Value)	  - this is the point in the size distribution, up to and including which, 90% of the total volume of material in the sample is 'contained'.

7)  %V < 10µ(Value)	  - this is the % of volume below 10 micron.

8)  D[4][3](Value)	  - this is the mean diameter over volume (also called the DeBroukere mean) value.

9)  D[3][2](Value)	  - this is the diameter of a particle whose ratio of volume to surface area is the same as that of the complete sample.

10) Cv(Value)	          - this is the The coefficient of variation (CV) is the ratio of the standard deviation to the mean. The higher the coefficient of variation, the greater the level of dispersion around the mean. It is generally expressed as a percentage.

11) Span(Value)           - this is a common calculation to quantify distribution width and is calculated by the following equation: (Dv90 − Dv10)/Dv50.
