VOC Testing of Gel-Form Fragrance – CARB Method 310

We require VOC (Volatile Organic Compound) testing by weight in accordance with California Air Resources Board (CARB) Method 310. Please confirm if your laboratory can perform this specific analysis on solid fragrance (gel form), including:
• Determination of total VOC content expressed as percent by weight (%)
• Full compliance with CARB Method 310 procedures (including thermogravimetric analysis, exemptions, and final VOC calculation by weight)
If your lab offers this service, kindly provide:
• Turnaround time
• Sample size requirements
• Cost estimate
• Any necessary sample submission forms or chain-of-custody documents

Testing method for your reference

If the regulated consumer product is –
(a) a non-aerosol product that does not contain LVP-VOC, the VOC content shall be calculated using the following equation –
Percent by weight of VOCs = (TV – A – H – EL) × 100
where –
• TV represents the weight fraction of total volatile material in the non-propellant portion, as determined by Method 24 or Method 24A, ASTM D2369
• A represents the weight fraction of ammonium in the non-propellant portion, as determined by ASTM D1426 or Method 300.7
• H represents the weight fraction of water in the non-propellant portion, as determined by ASTM D3792 or ASTM D4017
• EL represents the weight fraction of exempt compounds in the non-propellant portion, as determined by Method 8260B, Method 18, ASTM D859, Method 1400
(b) a non-aerosol product that contains LVP-VOC, the VOC content shall be calculated using the following equation –
Percent by weight of VOCs = [(1 – H) (1 – LVP) – EL] × 100
where –
• H represents the weight fraction of water in the non-propellant portion, as determined by ASTM D3792 or ASTM D4017
• LVP represents the weight fraction of LVP-VOC compounds and/or mixtures in the non-propellant, non-aqueous portion, as determined by ASTM D86, ASTM D850, ASTM D1078, ASTM D2879 as modified in Appendix B of Method 310, ASTM D2887, ASTM E1719, paragraph 3 of this Annex
• EL represents the weight fraction of exempt compounds in the non-propellant portion, as determined by Method 8260B, Method 18, ASTM D859, Method 1400
