Gravimetric Analysis

Our state-of-the-art environmentally controlled gravimetric laboratory is designed for one purpose — to achieve the highest quality gravimetric weights of small particulate matter.

Teflon Containers and Static Removal Control

From start to finish we use nothing but the latest technology to ensure accurate results. All weights are taken in lightweight, inert Teflon containers that marginalize container weight. Prior to weighing, static discharge (which makes accurate weighing nearly impossible,) is first removed from the container by passing it through an air ionization gate.

Analytical Balances

Our analytical balances are designed to produce the greatest accuracy and reproducibility at the low weight spectrum (1.0 milligram to 100 grams).This is the most common weight range for air test samples. Our balances are each linked to our gravimetric computer, with weights being transmitted to the data file by digital uplink. This ensures that weights are never incorrectly recorded by manual error. Archived weights for sample containers are also linked to data spreadsheets, further ensuring gravimetric analytical integrity.

We commonly perform gravimetric analyses for EPA methods 5, 17, 201A,202, 315, cascade impacter particle sizing, hi-volumetric particulate and a variety of state regulated air methods.

Reduce Your Hazmat Shipping Expense

Evaporate your solvent rinses (acetone probe washes, hexane impinger rinses etc.) on-site prior to shipment, and we’ll re-suspend your samples in our laboratory- saving your company hazmat shipping costs!
