Trace analysis

However, a hair tissue mineral analysis is much more than a test for minerals. Mineral Blueprint Providing a mineral blueprint of one's biochemistry, a hair tissue mineral analysis can provide pertinent information about one's metabolic rate, energy levels, sugar and carbohydrate tolerance, stage of stress, immune system and glandular activity. A hair tissue mineral analysis performed by Analytical Research Labs, Inc. It is a tissue mineral biopsy that is non-invasive, relatively inexpensive and extremely accurate.

Trace analysis

Part 1 By Paul Gaines, Ph. What is Trace Analysis? This difficulty may be caused by the sample size or the matrix i. Stages of a Trace Analysis Trace analysis - Prepare a plan that considers the objective. Planning should begin with a discussion between the analyst and the initiator during which all possible problems are defined.

The analyst is responsible for method selection or development. Sample Collection and Storage - Ideally the analyst is involved in this stage, but if not, the analyst should be informed of the sampling procedure at the very least.

Sample representation and contamination issues must be considered. Sample Preparation - Contamination issues are a major concern during this stage, but not the only concern.

Trace analysis

Sample Measurement - The major concerns during this stage are: Availability of Certified Reference Materials for method validation, plus stable and accurate calibration standards, interference standards, and quality control standards.

Achieving the required precision. It serves no purpose in acquiring a precision that has been reduced to less than one-third of the sampling error. In situations where the sampling error is small and the highest level of precision is required, the analyst faces a difficult task in acquiring precision equivalent to classical wet chemical techniques.

Obtaining the required sensitivity and determining the detection limit of the measurement.

Trace analysis

Overcoming interferences using ICP-OES that include matrix differences between standards and samples; spectral interferences i. Overcoming interferences using ICP-MS that include matrix differences between standards and samples; mass-discrimination effects; isobaric interferences; detector dead-time; and drift due to nebulizer plugging, changes in sample argon, power supply instability, or room temperature changes.

Calculating and Reporting the Data - Working with error budgets and calculating the uncertainty is the trickiest part of this stage. An article entitled Understanding Error Budgets is available online as an additional reference.

Training Trace analysis is extremely difficult. All too often, samples submitted as "routine" actually require highly skilled analytical chemists using complex chemical treatments and expensive state-of-the-art equipment.

Today, many analysts do not have the proper training, nor do they have access to a more experienced colleague that could offer assistance.

The availability of sensitive "push-button" instrumentation is ever increasing. Education should be provided for the analyst. Furthermore, job experience and training records should be kept and reviewed on an annual basis.
