Metals Testing Services

MACS Lab’s state-of-the-art equipment can give you fast, accurate results for your metal testing needs. Our easy-to-read reports meet all requirements of the accrediting bodies. We offer the following services:

CAM-17: Testing Waste for Hazardous Metals

Toxic Spill

The generation, transportation, disposal, treatment, and storage of hazardous waste is regulated in many states including California (CCR Title 22 Division 4.5). MACS Lab can test for hazardous metals in soil, groundwater, surface water, or wastewater so you can stay in compliance. We also test for asbestos in waste.

Laboratories testing samples for California regulatory purposes must be accredited by the California Department of Public Health (CDPH) ELAP program (Health and Safety Code section 100825). MACS Lab is fully accredited for Inorganic Chemistry of Hazardous Waste Analysis (FOT 114).

Our prices are competitive - as low as $100 per sample for 5-day turnaround. Turnaround times as fast as 24 hours are available (call for prices). Our easy-to-read reports include quality control data, so you know you are getting accurate results.

To submit your samples for analysis, indicate on the chain of custody form that you want CAM-17 analysis. We need just 5 grams of material for each sample. If you need TCLP or STLP extraction, see below.

TCLP and STLC Extractions

CAM-17 analysis determines the total concentration of each metal in the sample. The sample is prepared for analysis by ashing. We can alternatively test metals in TCLP and STLC extractions. TCLP (Toxicity Characteristic Leaching Procedure, EPA 1311) is an extraction method for soil to determine whether the waste is hazardous under the US Resource Conservation and Recovery Act (RCRA). We need a minimum of 120 grams of sample for TCLP.

STLC (Soluble Threshold Limit Concentration), also known as Waste Extraction Test (WET, CCR chapter 11 article 5 appendix II), is another test that is sometimes required for waste. We need a minimum of 60 grams of sample for STLC.

MACS Lab participates in the California Department of Public Health (CDPH) Environmental Laboratory Accreditation Program (ELAP). We are accredited for both TCLP and STLC extractions (FOT 115).

Other Metals

MACS Lab can also perform the following tests:

  • PP 13 (Priority Pollutant Metals)
  • RCRA 8 (Resource Conservation and Recovery Act)
  • LUFT 5 (Leaking Underground Fuel Tank)

or any set of elements from the following list (standard sets are shown):

RoHS Testing

RoHS compliance is essential to selling your products in markets from Europe to Asia. Let MACS Lab clear the path for you by providing accurate RoHS testing, compliance, and certification. MACS Lab is accredited in accordance with ISO/EIC 17025:2005 and has the quality management system to ensure you receive accurate results and authoritative certification of compliance. Each homogeneous material in a product must be tested separately. Your product is tested in our laboratory using sophisticated and accurate instruments.

The European Union directive 2011/65/EU restricts the level of six hazardous substances in electronics and other products. A number of other jurisdictions have similar RoHS legislation, including China, Korea, India, Taiwan, and California. Walmart has similar requirements. Cadmium is limited to 0.01% or 100 ppm by weight, and lead, mercury, hexavalent chromium, polybrominated biphenyl, and polybrominated diphenyl ether are limited to 0.01% or 1000 ppm by weight.

Custom Alloy Analysis and Fabrication

When repairing or replacing a metal part, you need to use replacement material with the same composition. But how do you know the exact alloy to use? In the absence of detailed records, you need to analyze the old part. That way you can be assured that the replacement material with have the same appearance and performance as the original. We have the instruments to analyze your material for 27 different elemental metals to determine the exact composition, and we can then produce new material of the same composition for your use in fabricating a replacement part or repairing the part.

Classic Car

Automobile Restoration

There have been over 4000 automobile manufacturers in the United States alone, and there were no standards for metal alloys used in cars. We can partner with you in your restoration project to produce alloys that have the same authentic composition as the original, assuring you of identical appearance and original performance, and protecting your investment. For example, MACS Lab analyzed a trim piece of one classic car for restoration, and produced material that matched the exact composition and appearance of the original. This car subsequently won Best of Show at Pebble Beach!

Every project is unique, so call the experts at MACS Lab for more information on our custom alloy services.

Technical information

CAM stands for the California Administrative Manual, also known as the California Code of Regulations. CCR Title 22 section 66261.24(a)(2) specifies 17 metals that can qualify waste as hazardous. The analysis method is also known as EPA 6010B/7400. CAM-17 metals analysis does not differentiate between different valences of chromium, and does not test for Fluorine.

ICP instrument

MACS Lab uses an Inductively Coupled Plasma (ICP) atomic emission spectrometer to analyze CAM-17 samples. For the technically inclined, this article by Bradford and Cook has a great deal of information about ICP instruments.

An ICP requires that the sample be extracted into a solution. Usually samples are extracted using ashing. TCLP and STLC extractions can be performed. Call for other extraction techniques that may be required in special circumstances.

CAM-17 analysis is most often used for soil and water samples, but can also be used for other materials such as rocks, minerals, sediment, air, alloys, and plant and animal tissue.
