Palintest Tubetests are integrated with the Palintest photometer system so as to provide a complete system for COD measurement. Palintest COD Tubetests are offered in four ranges: 150 mg/l, 400 mg/l, 2,000 mg/l and 20,000 mg/l.
The reagent formulations are based on those specified in recognised international standard methods and meet the requirements of conformity testing against national and international standards.
Four types are available, allowing the user to choose the most environmentally-friendly product for their application :-
§ The mercury-free formulation is recommended for general use
§ The formulation with mercuric sulphate (M) is provided for use in standard procedures which require the suppression of interference due to moderate levels of chloride
§ The high chloride formulation (2M) provides much higher levels of chloride suppression and is suitable for working with samples with very high chloride levels
§ The new M/C formulations with mercuric sulphate are specifically for use in non-Palintest instruments, and allow users of compatible instruments to take advantage of the price, quality, and service we offer, whilst using their existing instrumentation. The new product comes in three ranges: up to 150 mg/l, up to 1,500 mg/l and up to 15,000 mg/l.
