Bull & Roberts Introduces Test Kit Of Different Type For Boiler Feed Water A patented .and radically different type of test kit for the determination of dissolved oxygen in boiler feed water is being intro- duced to the marine field by Bull & Roberts, Inc. This new system, which is designed to speed the tests and give more accurate readings with far less material and equipment, will replace the most commonly used Winkler Test introduced by Bull & Roberts in the late 1930s. Deaerators on most modern vessels pro- duce feed water at or below 7 ppb (parts per billion) dissolved oxygen when operating at normal steaming rates. Whereas the Winkler Test will indicate "O Oxygen" when the con- tent is below 18 ppb, the new B&R Test Kit has standards of 0 and 5 ppb with graduations to 40 ppb to determine whether or not the deaerator is operating within specifications. Since any reading above 10 ppb spells po- tential trouble, and the approximate analysis time is only one minute, this test has real advantages to the engineer. In contrast to the Winkler Test which has a five-step proce- dure employing five different reagents, the B&R Test requires only one disposable am- poule, a sample purge bottle and a simple comparator containing eight color standards ranging from 0 to 40 ppb dissolved oxygen. In other dissolved oxygen tests, a measured volume of sample in an open container is, of course, in direct contact with the air. If the surface of the sample is stirred or agitated in any way, the test results will be invalid. In the B&R ampoule-type test, the sample never comes in direct contact with the atmos- phere. The tip of the ampoule is immersed in the flowing sample stream well below the surface of the water. When the test is run, the tip is broken off in the snapper fitting and the vacuum inside the ampoule sucks in the proper amount of sample. The initial kit setup consists of a sample purge bottle with special fittings, a compara- tor and a box of 30 ampoules. Thereafter, only additional cigarette-size ampoules con- taining a carefully measured quantity of col- or-forming reagent, sealed under vacuum, are needed. All materials or replacement parts are available directly from Bull & Roberts or from any of their distributors in major ports throughout the world. Bull & Roberts, Inc. is located at 785 Cen- tral Avenue, Murray Hill, N.J. 07974. GROUND BREAKING: M.K.
