A: One simple but very effective way to clean a microchip is to flush an alkaline solution through the channels. A solution of 1 M sodium hydroxide in water works well but a lower concentration might also be sufficient. If traces of the cleaning solution remaining inside the chip after cleaning and rinsing with water pose a problem then ammonia can be used instead. Note that the these solutions are caustic and can cause damage to e.g. the polyimide coating of fused silica capillaries. Also plastic parts should not be exposed to very alkaline solutions.
In order to aid in the removal of particulate matter a water bath with ultrasonic agitation in can be used, preferably while flushing a watery solution through the channels using an Fluidic connect kit.
Glass microchips can be heated (e.g. >400° C) causi ng any organic material adsorbed on the glass surface to degrade.
Concentrated sulphuric acid works well to dissolve organic material such as fibres which are difficult to remove with alkaline solutions, but because of the extremely corrosive nature of the material a cleaning procedure is not so easily implemented.
A: There are several high precision pumping systems on the market that work with different pumping principles. Many of our customers use for example the Fluigent pumping systems. Those systems are made to realize pulsation free, smooth and precise fluid delivery.
