Trial Number 3

Trial Purpose:

To determine if the aqueous cleaners are stripping the steel coupons provided by the company.

Date Run:


Experiment Procedure:

Three sets of three steel coupons were weighed and immersed into three distinct beakers containing Aquavantage 1400 GD, Liquinox, and SC-1000 respectively. Heated ultrasonics was conducted at 122-125°F for 15 minutes. Coupons were submerged in three distinct beakers containing deionized water as a rinse step for 5 minutes. Coupons were dried with an air gun for 10 minutes. Effectiveness of cleaning was observed gravimetrically after the drying step. 

Trial Results:

After 15 minutes of heated ultrasonics and subsequent post-treatment, coupons treated with Aquavantage 1400 GD and Liquinox lost a thousandth of a gram, while coupons cleaned with SC-1000 lost a hundredth of a gram.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.


Based on gravimetric analysis, Liquinox on average had the least amount of weight lost for the steel coupons. Coupons cleaned with both Liquniox and Aquavantage 1400 GD lost a thousandth of a gram. Coupons cleaned with SC-1000 lost a hundredth of a gram. The next step would be to continue testing with the vanishing oil contaminant provided by the company.
