cod digestion vials for measuring water quality Sigma

digestion. Mix contents of reaction vessels to combine condensed water and dislodge insoluble matter. 26 Is suspended material allo wed to settle prior to measuring absorption of each sample, blank and standard at the selected wavelength (420 nm or 600

With this test, you can measure virtually all organic compounds that can be digested by a digestion reagent. COD contrasts with biochemical oxygen demand (BOD), which relies on the use of microorganisms to break down the organic material in the sample by aerobic respiration over the course of a set incubation period (typically five days).

The HI93754E-25 COD kit contains 25 ready-to-use vials containing pre-measured reagents. These high quality reagents follow the mercury-free dichromate method for determination of COD. In this method, a heated digestion is required to oxidize organic matter in the sample.

Method: photometric, DMP 10 - 150 mg/l N Spectroquant®. The method is analogous to DIN 38405-9. The digestion is analogous to EN ISO 11905-1. This Spectroquant Nitrogen (total) Cell Test allows the reliable determination of total nitrogen in water samples. Total nitrogen is the sum of total Kjeldahl nitrogen (organic nitrogen and ammonia

COD rapid-digestion method. According to the relevant standard (ISO 15705), the COD determination with cell tests is performed at 148 °C, since the COD/water mixture in the cell already boils at this temperature. Higher digestion temperatures are thus not appropriate in this case. The conventional boiling time is 120 minutes: However, as
