Rinsing time

Ion exchange plant should be put into regeneration and inspected for correct sequence timing, backwash rate, regenerant draw, rinse times, and slippage from the service valve. 

Parameters that should be tested in HPLC method development are flow rate, column temperature, batch and supplier of the column, injection volume, mobile phase composition and buffer pH, and detection wavelength [2], For GC/GLC methods, one should investigate the effects of column temperature, mobile phase flow rate, and column lots or suppliers [38], For capillary electrophoresis, changes in temperature, buffer pH, ionic strength, buffer concentrations, detector wavelength, rinse times, and capillaries lots and supplier should be studied [35, 36], Typical variation such as extraction time, and stability of the analytical solution should be also evaluated [37],... 

Besides the flow rate, rinse times are very important. As discussed previously, if rinsing is insufficient to achieve the desired pH, deleterious effects can result. The example was given that if Te solutions are too acidic, bulk Te will form. 

Ultrasonic-assisted rinsing has recently been introduced to SILAR to shorten the rinsing time and enhance the effectiveness of the rinsing step. A commercial ultrasonic bath with a frequency of 50 kHz and a power of 100W has been used.11...

Moreovei rinsing procedures and equilibration conditions should be carefully described. Note that each type of instmment uses different pressure settings, so rinsing times cannot be directly transferred. Therefore, it is preferable to specify a rinsing volume or the product of pressure difference and rinsing time ° in the method which can be considered instrument independent. 

All functions are menu-driven. Parameters used for the running cycle (for example rinse times) may be changed by using a mouse or a keyboard changed parameters can be stored permanently. There is no need for the user to have any knowledge of computer programming.
