Liquid analysis - vessel cleaning

Fiber-optic UV-vis spectrophotometers are well suited to a clean-in-place application. For analytes with signals in the deep UV, best results will be obtained with a deuterium source and short fiber runs. Further out in the UV and visible regions, a xenon flash lamp

Inland transportation of methanol usually uses tank trucks, rail tank cars, or waterway vessels. The shipping containers should be dry and clean before loading. If the containers are not specialized for methanol transportation, analysis is usually required for each delivery. Each container must be appropriately labeled (such as U.S. Department of Transportation red label) for inflammable liquids. Additional cautionary labels (such as poisonous chemical) may be required by local authorities. Overseas transportation is by tankers. Regulations governing methanol transportation in selected countries can be found in Reference 6.
