HPLCThe system adoptsDursan ®Addressing the impact of stainless steel corrosion

InHPLCIf there is a nitric acid corrosion problem in the analysis, this corrosion leads to the loss of exogenous iron ions on the surface. The SilTek processing technology can effectively solve this problem.

This corrosion not only endangersHPLCThe integrity of the system leads to an increase in cost. It can form particles that cause pollution and blockage in the system, adsorb active compounds, and affect the analysis results. Corrosion of metal surfaces can cause retention, migration, and false positive results of proteins or viscous molecules.

The general steps of surface passivation technology are:

1clean the surface

Soak in nitric acid or citric acid for 30 minutes. (Different stainless steels use different acid concentrations and additives)

2、 用水wash

Test its passivation effect indoors in a humidified environment

However, this traditional passivation process requires the use of corrosive reagents such as bleach, hydrochloric acid, or electropolishing to achieve the passivation effect.

we introducedDursan ®The bonding process technology can eliminate the above-mentioned drawbacks by forming enhanced silicon compounds on the surface, which will make the stainless steel surface extremely corrosion-resistant and biologically inert.Dursan ®Process technology is a chemical vapor deposition process that, after treatment, prevents the flow path of stainless steel from damaging grain boundaries and forms a strong barrier against viscous compounds. adoptDursan ®Process technology coatingHPLCThe flow path can prevent hydrochloric acid and other corrosive media from causing surface pitting and other damage.
