Why DHA from Triton?

DHA by ASTM D-6623 utilizes the full separation power of modern high resolution capillary chromatography to provide isomer specific identification and quantification. WIth the power of over one million theoretical plates, the DHA method can quantify up to 300 individual components in a single run. The exponential number of hydrocarbon isomers limits the method to the C1 through C10 carbon number region. Gasolines may be analyzed up to C13.

Triton’s ability to combine the DHA technique with the GC/MS NOISE analysis allows unambiguous identification of carbon number and hydrocarbon type. This permits DHA to be applied to highly complex streams where conventional DHA databases are inadequate. An example of this may be found in the NOISE Tackles Gasoline paper.

Samples suitable for this technique include:

light naphthas,

crude oil and condensates (front end only),

Cat feed overheads (front end only),

gasoline blending streams including alkylate,

reformate, cat cracked gasolines,

and isomerates, etc.

For specialized chemical samples such as synthetic olefins or pyrolysis products ( py-gases, coker naphthas, etc.), Triton has developed an adjunctive DHA technique that utilizes an in-situ, real-time hydrogenation system which can convert olefins to paraffins in the GC capillary inlet. This allows determination of branching and double bond positions within synthetic olefin streams.

Sample Requirements: 5 ml
