TOC analyser principle

1. A Total Organic Carbon (TOC) analyzer measures the amount of carbon in organic compounds present in a sample. The principle behind a TOC analyzer is based on the combustion or oxidation of organic materials to convert carbon into carbon dioxide (CO2), which is then measured to determine the total amount of organic carbon in the sample. There are two main methods for measuring TOC: Non-Combustion Method (Oxidation Method) : The sample is oxidized, usually using a strong oxidizing agent like persulfate or UV light, to convert organic carbon into CO2. The resulting CO2 is then measured using a non-dispersive infrared (NDIR) detector or another detection method to quantify the total organic carbon. Combustion Method : The sample is heated to high temperatures (around 680–950°C), where organic carbon is combusted in the presence of oxygen to form CO2. The CO2 produced is then measured using infrared spectroscopy or other appropriate detection techniques. Both methods al...

TDS- Total Dissolve Solid

Total Dissolved Solids (TDS) testing for wastewater is a critical procedure outlined in the Standard Methods for the Examination of Water and Wastewater by the American Public Health Association (APHA). Specifically, the method referenced is APHA Standard Method 2540C: Total Dissolved Solids Dried at 180°C. Below is a detailed Standard Operating Procedure (SOP) for preparing and conducting TDS testing in wastewater, including a description of the method and a flow chart to illustrate the process. Standard Operating Procedure (SOP) for TDS Testing in Wastewater (APHA Method 2540C) 1. Purpose To determine the concentration of total dissolved solids (TDS) in wastewater samples using the gravimetric method as specified in APHA Standard Method 2540C. TDS measures the mass of organic and inorganic substances dissolved in water that pass through a filter, typically after evaporation at 180°C. 2. Scope This SOP applies to the analysis of wastewater samples (industrial, municipal, or environmen...

Standard Operating Procedure for the Measurement of Total Hardness

SOP For Total Hardness in Water and waste water EDTA Titrimetric method Purpose: The purpose of this protocol is to provide guidelines for analysis of Total Hardness in Water. Principle of method: EDTA and it's sodium salts from a chelated solution complex when added to a solution of certain metal actions, if a small amount of dye such as Eriochrome Black T is added to an aqoeous solution containing calcium and magnesium ions at a pH of 10+0.1 to 10-0.1, the solution becomes winr red. When titrated with EDTA , the magnesium and calcium will be complexed, and when all of the and has been complexed the solution turns from wine red to Blue. To Instrument/Equipment: The following items are necessary to perform the analysis of Total Hardness in Water; pH Meter Burette – 50 ml capacity Glass Wares Reagents/Chemicals: All the chemicals should be of Analytical Reagent Grade. Distilled Water Buffer Solution – Dissolve 16.9 g of Ammonium Chloride...
