Trial Number 3

Trial Purpose:

Measure characteristics of cleaner

Date Run:


Experiment Procedure:

To measure characteristics of cleaner to determine a relationship between cleaning efficiency and bath life. Measure %Transmittance & Absorbance @ 530nm, Sulfate & Sulfide concentration, and Turbidity of the cleaning liquid using LaMotte’s Smart Colorimeter.

SUBSTRATE MATERIAL: Liquid (cleaning bath, M-Auto)

Trial Results:

3/31/98 Bath %Trans Absorbance Sulfate Conc. Sulfide Conc. Turbidity
Reading #1 65 0.19 4ppm 0.51 4
Reading #2 71 0.15 4ppm 0.49 4
Reading #3 66 0.18 4ppm 0.42 4
Average 67 0.17 4ppm 0.47 4

Success Rating:

A cleanliness study, addressing only various analytical techniques.


Cleaning efficiency of the cleaning bath obtained from 3/31/98 will be determined after receiving a sample of the clients oil.  The results of the efficiency will be linked to the characteristics obtained in this trial so that a relationship could be determined.  With this relationship, bath effectiveness can be checked using the above testing methods.
