Spectral Analysis
PIMA™
can replace routine X-ray diffraction analysis for many applications, especially with clay minerals and other infrared active alteration minerals. Spectral International offers this spectral analysis service as a cost effective means for mineral identification.
The analytical service is offered for any number of samples. We run the sample with PIMA™, interpret the minerals present and provide selected, plotted spectra with references and an Excel log as seen below, which summarizes what we see in the sample.
This plot shows a mixture of jarosite(black arrows) and smectite(red arrows). The unknown is dark blue; jarosite reference is cyan; smectite reference is magenta.
The Excel Log has the following type of format:

We are pleased to provide further interpretation and comments on the alteration system and what the PIMA™ data is showing. This is an additional service.
Cost Schedule:
We prefer to quote each job separately. General costs include:
Basic analysis, with interpretation and identification log
| 1-19 samples | US$30/sample |
| 20-50 samples | US$25/sample |
| Larger number of samples are quoted on a per job basis and can be discounted further for higher volumes. |
We can also set up an account with monthly billings where samples are sent "as collected" or as the analysis is needed and the volume discount is applied.
| Additional Report writing | US$500/day |
| Core Logging |
| Mineral Percentage determinations | (quoted by the job) |
|

ON LINE SERVICES
Starting in May, SII will offer an on line mineral Identification services
1. Wavelength Search/Match access to SPECMIN
Seach by wavelength - the quickest way to a mineral ID
2. Dial into the FeatureSearch program.
The user can login, access the program and submit a spectral file, and interact with the program for an identification.
