Request for approval & information

Date Run:

09/12/1994

Experiment Procedure:

We are shipping out the samples for our cleaning comparison to be performed by the lab. We have made a couple of changes in the items:
1. The nickel piece is a large flat disc.
2. The monel piece is of two different configurations.
The samples will be labeled as follows:
Copper - #’s 1, 2, 3, 4 &5
Kovar - #’s 1, 2, 3, 4 & 5
Ceramic - #’s 1, 2, 3 & 4
Nickel - #’s 1, 2, 3 &4
Tungsten - #’s 1, 2, 3 & 4
Molybdenum - #’s 1, 2, 3 &4
Monel - #’s 1, 2 &3
Quartz - #’s 1, 2 &3

BACKGROUND: There are currently four chemical labs in our facility that process similar or identical materials independent of the others due to the fact that they belong to separate business elements. In most cases the cleaning/processing is slightly different for each department. We are currently in an effort to reduce our wastes produced as a facility. By doing so we are trying to consolidate our chemical lab processing.
PLAN: Send you (SCL) samples of selected parts (based upon the material) that have been cleaned by each of our departments utilizing that material. Then accompanying each part/material selection will be a sample that has been cleaned by a chosen new method. The new methods are ones that do not use chlorinated solvents, ozone depleting chemicals, are non-hazardous, etc.
We wish to compare the current methods to the new methods not only to prove in the new methods but to establish a baseline to compare them to.
Could you please look this information over and get back to me with your concerns and possibly a time frame that this work can be completed. If you need further information please do not hesitate to call. We will be speaking to you in the near future.

Trial Results:

OSEE readings were taken for all samples except for the Molybdenum due to its small size. For each sample, OSEE readings were taken at 10 second intervals for one minute. Due to the nature of Quartz readings, readings were not able to be taken every 10 seconds. The peak readings were taken instead. The average reading for the Quartz was 159.57 while the average reading for the Quartz #1 sample was 38.50. The results from all other OSEE readings are shown below.

Success Rating:

A cleanliness study, addressing only various analytical techniques.

Conclusion:

Goniometry tests were done on every sample except for the ceramic, quartz and molybdenum because of the shape of the samples.
