CoachTotal solid is the sum of all the solid components in a sample, including both organic and inorganic material. Total volatile solid is the portion of total solid that is lost as gas when the sample is heated to a high temperature, typically representing the organic content that is easily vaporized.

What is the difference between total dissolved solids and total suspended solids?
Total dissolved solids (TDS) refers to the amount of inorganic and organic substances dissolved in water, whereas total suspended solids (TSS) are solid particles that are suspended in water but can be trapped by a filter. TDS can include salts, minerals, and organic matter, while TSS typically consists of soil particles, organic matter, and debris. TDS is measured by filtering water through a fine filter, while TSS is determined by weighing the particles trapped on the filter after drying.
What is the difference between proximate and ultimate analysis?
Proximate analysis determines the moisture, ash, volatile matter, and fixed carbon content of a substance, while ultimate analysis determines the elemental composition (carbon, hydrogen, nitrogen, sulfur, oxygen) of a substance. Proximate analysis provides information on the physical and chemical properties, while ultimate analysis provides information on the elemental composition.
How can you check the solid content of Phenol Formaldehyde Resin?
The solid content of a Phenol Formaldehyde Resin can be checked using a method called gravimetric analysis. In this method, a known amount of resin is heated to remove the volatile components, and the remaining solid material is weighed to determine the solid content percentage. This provides an accurate measurement of the solid content of the resin.
What is fixed solid?
Fixed solid refers to a substance that remains in a solid state at a certain temperature and pressure. This term is often used in chemistry to describe solid compounds or elements that do not change their physical state under specific conditions.
What is the difference between Karl fisher and loss on drying?
Karl Fischer titration is a method for determining water content in a sample by using a titrant that reacts specifically with water. Loss on drying (LOD) is a technique that involves heating a sample to evaporate volatile components, such as water, and measuring the weight loss as a percentage of the initial sample weight. Karl Fischer is more precise and specific for water determination, while LOD is a general method that can include other volatile substances as well.
