FAQ

Q: How will results be reported to me?

A: We will email you a pdf report upon completion of analyses of your sample group. We can mail you a hard copy upon request.

Q. Do I have to submit an MSDs for every sample?

A: An MSDS must be supplied for each different substance and should be submitted with the samples. Manufactured items that present no health hazard do not need an MSDS, but you should indicate that on the submission form.

Q. Will I get my samples back?

A: Unused portions will be returned to you 30 days after results are reported (to allow time for a repeated test should it be deemed necessary).

Used portions that can be recovered may be returned or discarded at the discretion of the lab, unless you indicate that you require return of the analyzed (and recoverable) aliquot used.

Q. How much sample should I submit?

A: For surface area, pore size, chemisorption (including TPR/TPO/TPD) and water vapor sorption measurement we suggest a minimum sample quantity of 2g, except for zeolites, activated carbons and other high surface area materials, in which case 100mg should be sufficient.

True and tapped density measurements are best performed with as much material as you can provide up to 125 mL and 500mL bulk volume respectively.

Particle size analyses in liquid suspension or dry suspension require 1g and 5g respectively.

Zeta potential measurements can be done on 100mg of powder.

If you can send two or three times the indicated amounts, please do so... better to have too much than too little.

Q: Why do you ask for outgassing temperature?

A: For gas and vapor sorption measurements in particular it is essential that the samples be free of adsorbed moisture, not just visibly "dry". Therefore we normally outgas the samples by applying heat and vacuum (or purge flow of dry gas). It saves time and avoids problems with sample "damage" if you can indicate a safe degassing temperature. If you are in doubt as to what that might be, please contact the lab.

Q: Can you send me a copy of an ASTM method?

A: Due to copyright restrictions, we cannot supply copies of ASTM or other published standards.

Q: How can I inquire about the status of my samples?

A: You can email qmclab@quantachrome.com, or call 1-800-989-2476 and ask to speak to the laboratory regarding the status of your samples.
