The purpose of a dialyzer is to separate the analyte from interfering substances such as protein, whose large molecules do not go through the dialysis membrane but go to a separate waste stream. The reagents, sample and reagent volumes, flow rates, and other aspects of the instrument analysis depend on which analyte is being measured.
Hemodialysis, also spelled haemodialysis, or simply dialysis, is a process of filtering the blood of a person whose kidneys are not working normally. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure.
The growth of dialysis facilities in the United States is the result of more Americans developing end-stage renal disease. From 2001 to 2011 the number increased by about 49.7% from 411,000 citizens to 615,000 citizens. In 2001 there were only 296,000 Americans on some form of dialysis.
Schematic of semipermeable membrane during hemodialysis, where blood is red, dialysing fluid is blue, and the membrane is yellow. Kidney dialysis (from Greek διάλυσις, dialysis, 'dissolution'; from διά, dia, 'through', and λύσις, lysis, 'loosening or splitting') is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer ...
Dialysis is generally performed in clipped bags of dialysis tubing or in a variety of formatted dialyzers. The choice of the dialysis set up used is largely dependent on the size of the sample and the preference of the user. Dialysis tubing is the oldest and generally the least expensive format used for dialysis in the lab. Tubing is cut and ...
Kidney dialysis is the process of removing water, solutes and toxins from the blood of individuals with compromised kidney function, primary types of which are: Hemodialysis; Peritoneal dialysis; Hemofiltration; Liver dialysis, a detoxification treatment for liver failure.

Dialysis occurs throughout nature and the principles of dialysis have been exploited by humans for thousands of years using natural animal or plant-based membranes. [ 2 ] [ 3 ] [ 4 ] The term dialysis was first routinely used for scientific or medical purposes in the late 1800s and early 1900s, pioneered by the work of Thomas Graham .
Nils Alwall (October 7, 1904 – February 2, 1986 [1]) was a Swedish professor at Lund University, Sweden.He was a pioneer in hemodialysis and the inventor of one of the first practical dialysis machines.
