ET145-4 MCE chip with C4D electrodes (45mm)

1) Flush an alkaline solution through the channels, like 1 M sodium hydroxide in water. 2) A water bath with ultrasonic agitation can be used to remove particulated matters, keep energy levels initially low to prevent potential damages. 3) Glass microchips can be heated (e.g. 400°C) causing any organic material on the glass surface to degrade. Try to use lower temperatures first because burning the content could make it stick. 4) Concentrated sulfuric acid works well to dissolve organic material, such as fibres, that are difficult to remove with alkaline solutions.

Wet etched structures are extremely smooth and have a roughness in Angstrom range. The structures are fully optical transparent.

For EOF holder Chips: No interfacing solution availble For MCE Chips: Edaq has a platfrom available See "Read More" for details.

Yes there is! See "More details" for a link to a Wiki Page.

No, the chip only contains electrodes for contact conductivity detection. The electrodes for CE are part of the holder.

C4D is an abbreviation for Capacitively-Coupled Contactless Conductivity Detection, it uses a transmitter electrode to subject a sample region to a large amplitude, high frequency electromagnetic signal. A corresponding, attenuated, AC signal registers at a receiver electrode. See "Read More" for details.

The electrodes for C4D are located on the top surface of the chip, where also the inlet holes are located. There’s no direct liquid contact. The glass thickness between the electrodes and the channel is about 100 µm. See "Read More" for details.

Chips that have Micronit’s standard hydrophobic coating can be cleaned with most organic solvents.
