Technology Note 24
In all deionization processes there is a risk that weakly ionized impurities will elute from the resins and into your application as they approach exhaustion. PureSure® prevents this.
Technology Note 25
The PURELAB® Chorus 1 features a unique double purification pack and monitoring system providing a number of key benefits to the user.
Technology Note 26
The PureSure® system ensures removal of weakly ionized impurities, increased security and advanced warning of usable purification pack life in the PURELAB® Chorus 1
Technology Note 27
In a conventional water purifier, when a purification pack fed with RO permeate has reached the stage when output water purity drops below 18.2 MΩ-cm, it is necessary to change the pack in order to maintain water purity. The life of a purification pack is extended in PURELAB Chorus 1.
Technology Note 28
Measuring Total Organic Carbon (TOC) is a useful universal indicator of the rpesence of organic impurities. By constantly monitoring TOC we can be assured of the overall organic purity of the water.
Technology Note 29
The serious consequences of organic contamination of ultrapure water have resulted in the widespread use of Total Organic Carbon (TOC) monitoring in addition to resistivity as key indicators of water purity.
Technology Note 30
The PURELAB® Chorus 1 provides ultrapure water directly from a pretreated water supply. When fitted with an ELGA Biofilter it provides water, which is effectively free from biologically active impurities.
Technology Note 31
Endotoxins are lipopolysaccharides (LPS) which shed from the outer membrane of fram-negative bacteria. Reliable experimentation involving cell division, electrophoresis and other biochemical processes all benefit from the removal of endotoxins.
Technology Note 34
Carbon dioxide (CO2) degrades the resistivity of purified water and since it exists in equilibrium with carbonic acid (H2CO3)when dissolved in water, lowers the pH.
Technology Note 35
Reverse Osmosis (RO) is a separation and concentration process. Water with impurities is fed under pressure to a semi-permeable membrane and some of the water crosses the membrane, leaving virtually all the impurities behind in the remaining water.
Technology Note 36
Short wave (UV-C) light has been used sinced the early 1900s for bacterial control and TOC reduction in water. The use of UV light in our systems is to provide maximum germicidal effectiveness.
Technology Note 37
After organic and inorganic chemical impurities are removed, bacterial growth can still occur. If this bacterial growth is not minimized, it can cause problems to the purity of the water required which may impact on any test work results.
