WETLAB Develops Best Practices for Lithium Brine Analysis

WETLAB is an analytical facility, so our area of expertise lies in our ability to achieve accurate results with relatively low reporting limits for difficult matrices such as brine solutions. In the past year, WETLAB has seen an increase in the submission of brine solutions for lithium analysis. WETLAB partners with consulting firms, soils, and geochemistry laboratories to provide a complete and precise set of data, with each team contributing from their strengths. Through analysis we’ve gained valuable knowledge and experience and have developed best practices to best analyze this difficult matrix.

As far as analytical difficulties with this matrix, there are several:

  • Li is a very light element. This precludes it from some testing methods outright (such as XRF/XRD).
  • When Li is in a matrix with a large number of heavier elements, it tends to be pushed around and selectively excluded due to its low mass. This provides challenges when using Mass Spectrometry.
  • A brine matrix also has the potential for much greater interferences regardless of method used.
Li Brine Testing

Lab Testing via Ion Chromatography

At WETLAB, we have handled many Li Brine solutions and extracts, which has given us a chance to gain experience and fine tune our methodologies to meet our clients’ needs. By using different phase-testing and isolation techniques, we are able to provide a good overall picture of the complete sample in situ. We have often tested the solid, aqueous, and slurry components individually from single samples to provide a fuller understanding of the mineralogy present.

Our low reporting limits allow us to complete the analytical process with a smaller initial sample size which saves time and cost when it comes to extractions and shipping. We are also able to do larger dilutions to eliminate or reduce interferences while further reducing native sample consumption.

We have the use of a full laboratory at our disposal, with staff experienced with difficult matrices and samples with high potential for interference. This allows us to provide other analytes with good accuracy and relatively low reporting limits. The complete profile can allow field specialists to determine the appropriate steps to drive their operation with less guess-work. For instance, we were able to provide quick and meaningful results for Iron and Phosphate for a client who suspected their Lithium was in a Lithium Ferrous Phosphate.

We are always happy to field any analytical-related questions at any time.

    We have some brine water evaporated raw material to be tested for Lithium, the material is in Afghanistan, please let us know if how we can send the material for testing and how to take the sample and also the provide us the quote for it.

    Thanks

    Hi:

    I need a price quote for multiple sample analyses of clay and brine for lithium along with turn around time.

    Thanks,

    Jim Lynch
