Project specific full calibrations for each analyte. (Some labs use a single point calibration for a correction factor that is then used with an old full calibration.

Full instrument calibration immediately before and immediately after sample analysis for every project. All calibration data are included in our report.

Look for the full calibration dates listed on the calibration page.

Some instruments have non-linear drift.

This is problematic with a single point calibration.

Single point calibrations can produce bad results with no evidence of error.

Many methods only require three calibration points to generate a curve. This is the bare minimum for establishing a straight-line relationship.

All of our calibration curves include at least one more point than required by method. This is a minimum of four calibration points with a coefficient of regression (R2) value greater than 0.995.

Calibration curves and least-squares regression data. Look for coefficient of regression (R2) greater than 0.995

With an R2 of 0.995 or greater, the possible error is around 0.5%. A lower R2 value suggests a greater possibility of error.

The calibration curve is not very accurate or precise when the R2 value is under 0.995.

Sample Contamination

We minimize lab contamination by limiting our analysis services to relatively clean air samples.

     

Samples may not fall within the concentration range the instrument was calibrated for.

Calibration curves are customized to each project, minimizing the need for diluting samples

That the calibration curve brackets all reported concentrations for the samples.

Note: sample dilution may be required, but should be kept to a minimum.

Diluting samples can introduce error into the analysis

Humidity and temperature control
