Abstract
Abstract A method for automatically performing distillation analysis of liquids wherein a sample of the liquid is vaporized while the temperature of the vapor and the weight of the sample are continuously measured and recorded. The method also provides for supplying the data to a computer programmed to provide preset percent distillation points for the sample and hold circuits that can be set to trigger at any preselected boiling point or cut point.

Claim 3
Dependent Claim
38 words
The method of claim 1 wherein the measured temperature corresponding to a second pre-selected cut-point is determined and used to control the amount of a second liquid added to said blend to control the density of said blend.
Claim 4
Dependent Claim
27 words
The method of claim 2 wherein said first pre-selected cut-point is less than 50% and said second pre-selected cut-point is more than 50% of the total sample.
Claim 5
Dependent Claim
31 words
The method of claim 2 and in addition measuring the density of said blend and using said density measurement to determine the weight of each liquid added to the sample tube.
