As of August 6th, 2015 Express XRF Analysis will be relocated from Bakersfield, CA to Turlock, CA. Our new address is:

Express XRF Analysis
2930 Geer Rd 131B,
Turlock, CA 95382

Please take note of this address change when sending samples. Our previous address off of Mall View Rd will still be checked on a regular basis as we make this transition, however, if you need a rapid turnaround on your material, sending your samples to the old address will most likely cause a delay in processing.
