Because the work is scoped per project, a useful quote request would describe the material or alloy, the test needed such as PMI, XRF, OES, liquid penetrant, magnetic particle, ferrite, hardness or metallurgical evaluation, the specification or standard to be met, the number of pieces or samples, and whether the testing is to be done in the Houston lab or on-site at a plant or job site.
The site does state a 24 hour report turnaround, but it does not tie that to any price and does not state current availability or scheduling.

The about page describes the service area as clients in Houston TX and surrounding areas, and says CDJ has served many clients there. It also refers to labs in the Texas area, but the site does not define a mileage radius, list specific cities or counties served, or name any branch or second location. Because CDJ offers on-site as well as in-house laboratory services, work can be performed at a customer's plant or in the field using mobile instrumentation, but the site does not state how far the on-site crews will travel. Confirm coverage for a particular location by calling the office.
The contact page carries a form asking for name, company, phone, email and comments, with the note "Complete the form below and we will be in touch soon." There is no online booking or appointment calendar on the site, so a booking or schedule request is made by phone, by email or through that form. The site does not state appointment lead times or when the lab can take in a job.

It states that full chemical analysis, including light elements such as carbon, can be performed using optical emission spectrometry for precise material grade identification or to re-establish material traceability.
Non-Destructive Testing / Material Evaluations: the page says PMI and chemical analysis can be performed in a totally non-destructive or semi-non-destructive manner, and also lists Liquid Penetrant examination (LP), Magnetic Particle examination (MP), Ferrite testing and various hardness testing capabilities to evaluate material physical properties.
- Laboratory Metallurgical Testing
- full laboratory chemical analysis using stationary OES and combustion/fusion determination of C, S, N and O, along with destructive mechanical testing, metallography and micro hardness testing.
Materials listed as tested are carbon steels, low alloy steels, tool steels, stainless, nickel base, cobalt base, copper base, aluminum base and titanium base. Listed applications are weld verification, positive material evaluations for ASME, ASTM, AWS and API standards, and OEM vendor surveillance.
No prices, rates or fees appear for any of these services. Contact the Houston office at 713-895-8855 to discuss a specific scope of testing and request a quote.
