Analytical Services Laboratory (ASL)
The ASL is under the extension function arm of the Institute of Chemistry. It is primarily a teaching and instructional laboratory of the Institute for the chemical instrumentation courses and other chemistry courses where instrumentation is a requirement. The ASL extends its analytical services to both government and private customers.

If you find the service you need, email aslchem.upd@up.edu.ph for consultation with the following details (incomplete inquiries will not be entertained):
- Full Name
- Affiliation (School/Company)
- Service/s requested
- Detailed description of samples (solid/liquid, solvent used, etc.)
- Purpose/objective of the analysis
- Number of samples
- (Optional but highly recommended) Photo of sample
Important Reminders:
- Check our list of services before emailing; we will not respond to inquiries about unavailable services.
- Incomplete requests will not be answered. Ensure all required details are included in your email.
- Allow at least 3 working days before following up. Emails are answered in order of receipt, and follow-ups will only push your inquiry further down the queue.
- We do NOT offer rush services.
- Rates are already discounted by client type (Type 1, 2, 3). No further discounts will be provided.
- Laboratory access is not permitted for safety reasons. Requests to use our facilities for experiments will not be entertained.
- We do NOT offer documentation services. If documentation is required, please seek the services of other laboratories.
- Walk-ins are not allowed. All appointments must be confirmed via email, and slots are limited.
Once your samples are confirmed as compatible with our equipment and protocols, we will schedule an appointment (available only on Mondays with limited slots). Required forms will be sent upon confirmation and must be presented on your appointment date.
Turnaround Time:
- Rotary evaporation extracts: 5 working days for every 2 liters of sample.
- Certificate of Analysis: Minimum 15 working days from sample submission date.
- Do an online consultation by sending an e-mail to aslchem.upd@up.edu.ph.
- Request an appointment by sending an e-mail to the same address.
- On the appointment day, fill out the Request for Analysis Forms (UPIC-ASL Form 1 P1 and P2; you may click on the Forms tab above to download). Submit the sample for assessment and labeling.
- A charge slip will be issued containing the appropriate service fee. Bring the charge slip to the UPD Cash Office and pay the service fee.
- Take a picture of the Official Receipt (OR) and send the file to aslchem.upd@up.edu.ph.
