Pigmenturia and phenothiazine may result in a false-positive reaction; false-negative reactions may occur with large amounts of urinary ascorbic acid vitamin C. Minimum shelf-life of the pH-indicator papers a n d pH-indicator strips millipore. Performance testing on these strips have been extensively exercised in the presence of metals and ions. Examination of unstained urine is recommended for routine samples. Field Of The Invention This invention relates to a colorimetric process for the semiquantitative detection of peroxides, especially ether peroxide, using a peroxidase-containing indicator. Use in Organic Solvents It is generally recognized that ether peroxides are dangerous.
Dissecting Instruments. Dilute to the required strength. These and other objects of this invention will become more fully apparent to those skilled in the art from the following description of the invention. A test strip is immersed in a solution of 50 mg. Parasitic ova observed include those of Stephanurus dentatus , Capillaria plica , C felis , and Dioctophyma renale.

A positive reaction can be due to hemorrhage hematuria , intravascular hemolysis hemoglobinuria , or myoglobinuria. All-in-one incontinence briefs featuring soft, breathable and water-repellent reinforced non-woven side panels covering the. Measuring range and number of determinations Cat. The sample solution should be between pH 2 and A process according to claim 1, wherein said moist gas is air having a relative humidity of about 90 percent.
The Peroxide Test detects inorganic and organic compounds containing a peroxide or a hydroperoxide group. The sensitivity of such test strps for organic peroxides, especially ether peroxides, generally is too low to permit semiquantitative determinations. Provide Content Correction. Glucosuria increases the SG despite increased urine volume. Custom Services and Products.
