ANALYSIS

Plating Resources, Inc. offers laboratory analysis of hard chrome plating solutions. The results are promptly faxed back to you and recommendations are made for any additions or treatments that may be needed. This includes tracking of typical contaminant levels.

We fully understand the chrome process and will assist with any concerns or problems you may be having. Most commercial laboratories are not qualified for this as they do not understand chrome plating so errors and inadequate advice is common.

Analytical Procedure click here.

Frequency:
The following should be performed for each 200 amp. hours per gallon of bath volume. This equates to a 1,000 gallon bath operated at 5,000 amps. on a single shift for a 40 hour week, or 200,000 amp. hours of operation.

Basic Analysis:

1 / week

(chrome & sulfate only)

Complete Analysis:

1 / month

(all ingredients & contaminants)

Expanded Analysis:

1 / Year

(all metals, organics & bath conductivity)

Most shops perform the basic analysis in- house. It is critical, however, to also test the trivalent, chloride, catalyst, iron, copper and insoluble levels on a regular monthly basis.

Special accuracy grade reagents and analytical procedures are available for companies that wish to do their own analysis.

Bath Sample Instructions

  • If needed, fill the tank to it’s operating volume with water. Be sure that the bath is thoroughly agitated and that any water addition is mixed in completely.
  • Using a small plastic bottle, take a sample of the bath from at least three (3) points in the tank. No more than a 150 milliliter sample should be provided, see note below. If a larger bottle is used, pour off any additional quantity until only approx. 150  mls.remains. 150 mls. is equivalent to approx. 1/3 pint or 5 fluid ounces. This small sample size avoids the $50.00 hazardous material disposal fee that would normally be charged.
  • Tighten the cap, rinse the bottle, wipe it dry and then seal the cap with vinyl tape.
  • Fill out the sample tag shown below and place it on the bottle. Please make copies of this page for multiple samples & for future use
  • Insert the sample bottle into a plastic bag and seal the bag so that it is waterproof. Pack this into a heavy duty cardboard box along with plastic peanuts for cushioning. Do not use paper.
  • Ship it, freight prepaid to:
Plating Resources, Inc.
2845 West King St. - Unit 108
Cocoa , Florida , 32926
  • Follow all DOT shipping regulations.
