Question

What's the difference between colloidal impurity and suspended impurities?

Answer 1

The varied sources of impurity in pharmaceutical products are — reagents, heavy metals, ligands, catalysts, other materials like filter aids, charcoal, and therefore the like, degraded end products obtained during and after manufacturing of bulk drugs from hydrolysis, photolytic cleavage, oxidative degradation, decarboxylation.

Complete answer:

Colloidal Impurity	Suspended Impurity
Some of the molecules are agglomerated with the boundary surface between the solid phase and water. These impurities are called colloidal impurities.	Suspended impurities are suspended solids that aren't completely soluble in water and are present in particles.
A colloid is made when particles are sized between 1 and 1000 nm.	A suspension is for particles larger than 1000 nm.
It's a mix between a homogeneous and heterogeneous mixture.	This problem occurs thanks to contact with suspended matter and elements like sand, rocks and organic matter.
An example of a colloid would be Jello or any gelatinous mixture.	The foremost common example of this is able to be sand in water or dust in air.
The particles will stay suspended permanently within the solution.	The particles overlap to remain suspended within the solution and can fall out over time.
Colloidal impurities in water include organic waste products and amino acids.	Suspended impurities cause the water to become turbid.

Note:
These impurities in water are what we seek to exclude from beverages. The kinds of impurities in water can include dust, dirt, harmful chemicals, biological contaminants, radiological contaminants, and total suspended solids (TSS).
