Tags :

Category : news

ARI will be closed November 28th for Thanksgiving and operating with limited staffing on November 29th. BOD sample requests will not be accepted on November 23rd and coliform and Cr6+ sample requests will not be accepted on November 27th.

If you have any questions about sample delivery over the holiday week please contact your project manager or navigate to our contact page to email or call the team.


SW-846 and EPA 600 Series Method Transition Schedule

On September 3, 2019 ARI will be begin the transition to SW-846 method versions SW8270E, SW8260D, SW6010D, and SW6020B. All the specifics regarding the transition can be found in this post for the organic methods and this post for the inorganic methods. The method assigned to the samples on or after this day will depend on the accrediting agency for the project beginning with work done under WDOE. ORELAP and DoD related projects will follow later pending accreditation.

WDOE accreditation for EPA methods 625.1 (semi-volatile) and 624.1 (volatile) has already been approved. Please see the recently updated WDOE scope for the full list of accredited analytes.

Eventually ARI will no longer log analytical requests for the previous versions of those methods once all the replacement accreditations are issued. If you have questions regarding the changes and what it means to your project please contact ARI directly via your project manager or using the website contact form.


Soil TOC Analyzer

New Technology Highlight-Elementar TOC Cube

Category : news , technology

Classic analysis methods for Total Organic Carbon (TOC) required extensive pre-analysis preparation including multiple drying steps, grinding, and acidification. With the purchase of the Elementar TOC Cube Analytical Resources is now able to analyze for TOC, Total Inorganic Carbon (TIC), and Residual Oxidizable Carbon (ROC) without all the time consuming preparation and still improve on reproducibility with faster, unattended, sample throughput.

Sample analysis sizes used in the Elementar TOC Cube are allowed to be on the order of grams which allows for more representative analysis of non-homogeneous sample matrices. True matrix spike samples can be created, as opposed to post-spike samples where the spike is introduced at analysis, providing a more accurate QC measure of the method.

With this investment in instrumentation and training ARI is able to provide higher quality analytical results with a shorter TAT. Contact your project manager directly or use our contact form to learn more about pricing, reporting and control limits, and options for TOC, TIC, and ROC analysis.

Upcoming Version Transition for Metals Methods SW6010 (ICP-OES) and SW6020 (ICP-MS)

Around late summer 2019 ARI will be transitioning the primary analysis method versions for metals analysis by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) from SW6010C to SW6010D and for Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) from SW6020A to SW6020B.

ARI specific details regarding the differences between the SW6010C and SW6010D versions are noted in the linked table below.

ARI specific details regarding the differences between the SW6020A and SW6020B versions are noted in the linked table below.

The actual date for the transition will be published in a future post and clients will also receive notification through ongoing outreach from the ARI Client Services team. Any questions about the upcoming transition not answered in the above tables can be directed towards your project manager or reach out to ARI directly and a staff member will assist you.


Upcoming Version Transition for Methods SW8270 (SVOA) and SW8260 (VOA)

Around late summer 2019 ARI will be transitioning the primary analysis method versions for semi-volatile (SVOA) parameters from SW8270D to SW8270E and for volatile (VOA) parameters from SW8260C to SW8260D. This transition applies to both the full and selected ion monitoring (SIM) applications of the methods.

ARI specific details regarding the differences between the SW8270D and SW8270E versions are noted in the linked table below.

WAC 170-300-0235 Safe Water Sources

Category : news

With the adoption of WAC 170-300-0235 on May 27, 2017 all early learning providers in the State of Washington are required to test drinking water supplies for lead and copper every six years with the first test required within six months of the law becoming effective. Analytical Resources provides testing services for both metals and the necessary documentation for regulatory compliance. See our Drinking Water analysis page for details or contact Analytical Resources for more information about sampling, pricing, and turn around time.
