Summary of method. 2.1 A volume of filtered sample that will yield less than 200 mg residue is evaporated just to dryness on a steam bath. The residue is dried at 105°C for 2.0 h, cooled in a desiccator, and immediately weighed.National Water Quality Laboratory. Science. Residue on Evaporation (ROE) This analysis determines the mass of the residue left behind when the water in the sample is evaporated at .

1.1 This test method covers the determination of dissolved organic and inorganic matter and colloidal material found in high-purity water used in the semiconductor, and related industries. This material is referred to as residue after evaporation (RAE). The range of the test method is from 0.001 μg/L (ppb) to 60 μg/L (ppb).Evaporation Residue Tester can test the dissolving-out amount of test sample soaked in specified liquid.

3.2 This test method for residue by evaporation tends to give an asphaltic residue lower in penetration and ductility than the distillation test method (D6997). Material may be accepted but shall not be rejected as failing to meet specifications containing requirements for determination of residue by distillation, on data obtained by evaporation.
3.1.1 carbon residue, n—the residue formed by evaporation and thermal degradation of a carbon containing material. 3.1.1.1 Discussion—The residue is not composed entirely of carbon but is a coke that can be further changed by carbon pyrolysis. 4. Summary of Test Method 4.1 A weighed quantity of sample is placed in a glass vial The term “SAP” in the context of acetic acid glacial testing likely refers to the “Saponification Value” or “Saponification Acid Value.” The Acetic Acid Glacial Testing Procedure (SAP) saponification value is a measure of the average molecular weight of all the fatty acids present in a substance. It is often used in the analysis of fats and oils.
As the residue left by the distilled alcohol seems to be "highly non volatile" rather than acting on the distillation, a long column should prevent escape of aerosol. A 20 cm vigreaux is certainly short, especially if nested on flask of the liter scale! $\endgroup$ This test method covers the determination of non-volatile matter, that is, residue on evaporation, in solvent extract from aerospace components, using a rotary flash evaporator. The summary of the test method, the apparatus for testing, reagents and materials for testing, and procedure for testing are all presented in details.astmd693422-Standard Test Method for Residue by Evaporation of Emulsified Asphalt- 1.1This test method covers the quantitative determination of residue in emul .

The NaOH they add to it is to prolong shelf life. And the reaction by which sodium hypochlorite is reduced to sodium chloride consumes protons, producing even more hydroxide, so it's indeed possible that residual alkali is causing the irritation the OP is describing.
non volatile residue testing
The Japanese Food Sanitation Act designates the evaporation residue test as a specification for plastics that intended to contact with foods. The test conditions and migration limits for oils and fatty foods were considered on the basis of the results obtained from the evaporation residue test according to the Japanese Act and the overall migration test into olive oil according to .1.1 This test method covers the determination of the amount of carbon residue (Note 1) left after evaporation and pyrolysis of an oil, and is intended to provide some indication of relative coke-forming propensities.This test method is generally applicable to relatively nonvolatile petroleum products which partially decompose on distillation at atmospheric pressure. Its rapid evaporation rate means it leaves surfaces dry and residue-free. Availability: It is readily available in most pharmacies and stores, making it accessible for everyday use by the general public.

1. Calculate the percentage of residue for each sample, as follows: Residue, % = 4 × (M a -M b) where: M a = Weight of the container and asphalt emulsion residue in grams, and M b = Tare weight of the container in grams. F. REPORTING OF RESULTS Report the percentage of residue by evaporation as the average of the three results. G. PRECAUTIONS Visual appearance of a disinfectant residue on a surface may not always correlate with the amount of residue indicated by a residue on evaporation test. Since all disinfectant residues are not the same, it is also important to understand how readily the disinfectant residue is removed from equipment, surfaces, floors, walls, ceilings and windows. We found that during evaporation, droplets on the tested surfaces first shrink in height (constant contact radius mode) and then in diameter (constant contact angle mode) to form a thin liquid film, leaving behind residues of different types on the order of micrometers, as illustrated in Fig. 1.We either obtain a single residue, most likely a thin film or droplet, or .
Cleaning and disinfection are necessary protective and reactive steps to address microbial deposition on surfaces within pharmaceutical cleanrooms. An appropriately designed cleaning and disinfection program plays a central role in a contamination control strategy. There is considerable literature on the importance of cleaning and with disinfectant selection. In .This test method describes the procedure to determine the percentage of asphalt and latex (combined) in an asphaltic emulsion. The residue from this test may then be used for additional testing. This test is a modification to Section 7 of AASHTO T 59-15. B. REFERENCES AASHTO T 59 -15 – Standard Test Method for Emulsified Asphalts

Cooling and weighing the residue: After evaporation, the dish is allowed to cool to room temperature in a desiccator and then re-weighed to determine the weight of the nonvolatile residue. Calculation: The nonvolatile matter content is calculated by dividing the weight of the nonvolatile residue by the weight of the original sample and .
