Sampling & Analysis
POLICIES + QA REFERENCE
Standard filter cassettes, sorbent tubes, specialized filters, tubes, impinger solutions are supplied free if the samples are returned to our labouratory for analysis. Certain passive monitors are also supplied free if the samples are returned to our labouratory for analysis and you are not already receiving a volume discount for work. Media not requiring refrigeration can be shipped via UPS ground at no charge. A purchase order or credit card authorization may be required prior to the shipment of media. Media not returned to our labouratory with samples for analysis will be billed after sixty (60) days.
One blank should be submitted for each type of analysis requested in a given batch of samples, even if the batch consists of only one sample. If a blank is not submitted, we will add one upon receipt of your samples. Should you prefer that we not add a blank, please make note of this on your Chain of Custody form. Blank samples will be charged at the normal sample rate. See our Sampling & Analysis Guide and fee schedule for analytes requiring additional blanks.
Desorption efficiency (DE) varies with the lot of sorbent, concentration level, and with the number and types of compounds co-absorbed. Extra sampling tubes should be submitted with samples for the most accurate determination of DE. If tubes are not submitted, DE corrections will be based on existing labouratory data. Non-routine compound DE determinations will be performed as needed, and will be charged at the normal analyte fee.
For industrial hygiene analyses, we follow the current NIOSH Manual of Analytical Methods, OSHA Analytical Methods Manual, and other state or federal procedures. In addition we offer analytical method development services for proprietary compounds and other non-routine analytes.
Save time and money – Some analytes can be collected on the same medium and analyzed together. Compounds with the same compatibility Code in the Sampling and Analysis Guide may be collected on the same medium. See the comment section column for analytical discounts. Please review our Universal Solvent list under the Sampling & Analysis section of this site for further assistance.
AIR SAMPLING PUMPS
Sampling pumps are available from SGS Galson through our FreePumpLoan program. Various pumps with all the necessary sampling accessories are available for loan. The customer is responsible for the shipment of the pumps to the sampling destination and back to the labouratory. Call us for more details.
SGS Galson realizes how important timely results are to our clients. We guarantee a five-day turnaround for routine industrial hygiene analysis. Results are faxed or e-mailed by 6 p.m. EST on the fifth working day following the day of sample receipt. A few non-routine analyses typically require more than five days to analyze, these exceptions are noted with an asterisk in the analytical technique column of the analyte listing. Rush turn-around can also be provided. Please confirm rush samples in advance by contacting our Client Services Department. The following surcharges will be added to the listed fees for results reported by 6 p.m. Eastern Time:
|Next day (12pm)||150%|
|Next day (6pm)||100%|
For example, if the listed fee for one sample with normal five business day turnaround time is $50.00 the following table would list what the cost including surcharges would be based on the following expedited turnaround times:
|Turnaround||Cost per sample|
|Same day 200%||$150.00|
|Next day (12pm) 150%||$125.00|
|Next day (6pm) 100%||$100.00|
|Second day 75%||$87.50|
|Third day 50%||$75.00|
|Fourth day 35%||$67.50|
Results are faxed or e-mailed at no additional charge. If a hard copy report is required it will be mailed within 24 hours of the time the results are faxed or e-mailed.
A few analyses require a subcontract labouratory. These analytical results are typically provided within 10 business days. Reports are provided to you in their entirety as soon as our labouratory receives them.
FEES AND DISCOUNTS
Reduced fees are available for more than one organic vapor, metal, or inorganic acid on a single sample. See the comment section in the Sampling & Analysis Guide. A 10% discount is applied to twenty (20) or more identical analyses when submitted at one time.
All sample results and labouratory reports are strictly confidential. Results will be provided only to the addressee specified on the Chain of Custody form submitted with the samples unless law requires release. We will require written permission from the addressee to release results to another party.
Unless previous arrangements are made, all samples are disposed of 14 days after the report has been issued.
SGS Galson warrants the test results to be of a precision normal for the sample type and methodology employed for each sample submitted. SGS Galson disclaims any other warrants, expressed or implied, including warranty of fitness for a particular purpose and warranty of merchantability. SGS Galson accepts no legal responsibility for the purpose for which the client uses test results. Our Standard Terms and Conditions govern any analytical work performed. Prices, methods and detection limits may be changed without notification. Please contact your client service representative for the most current information.
A completed credit application must be on file for us to extend credit. Purchase orders or credit card information must be submitted for us to release sample results. Payment terms are net 30 days. A monthly charge of 1.5% of the unpaid balance will be charged after 30 days. In the absence of an established credit arrangement or authorized purchase order, all analyses must be prepaid. We accept payments by Visa, MasterCard, American Express, Discover and Diners Club.
LIMITS OF QUANTITATION
The quantitation limits provided within this guide are the most current limits determined at the time of printing. The limits are actual labouratory determined limits and are recalculated periodically in accordance with our Quality Assurance requirements. These limits are subject to change; however, they will seldom change significantly. Please contact a client service representative if the exact limit of quantitation is required.
