How can I exchange H2O for D2O in soluble collagen type I at pH 2?

I have collagen type I dissolved in a 0.01M HCl solvent (pH 2), and need to exchange the majority (99%) of the H2O to D2O. I am thinking that dialysis against a corresponding 0.01M DCl D2O...

Hi Patrik, you may try PsychoPy or OpenSesame open source softwares i found it useful to generate stimuli and you can send the trigger through parallel port.

Hi,

I used to send triggers to EEG and fNIRS recording devices using E-Prime through the serial port and the parallel port simultaneously. As E-Prime can not send wireless signals (as soon as I know), you should use a converter to convert the signals to wireless forms through the serial port or the parallel port.

Best regards.

Hi here are some informations from datasheet.

If you bought it through BIOPAC inc., check up below.

http://www.biopac.com/Product_Spec_PDF/Mobita.pdf

At least BIOPAC OEM version of mobita can receive TTL trigger through custom-designed EEG cap assembly.

If you need wireless TTL trigger, it seems quite tricky. One possible solution is using light sensor. (check out stimtracker from Cedrus and sync mechanism of fast-camera system from Biopac and you can get some ideas.)

Dear All,

thank You all for the answers. I'll have a look to all the advices.

Best regards,

Hi Patrick,

Is this question still relevant, otherwise I am happy to help you. The way the Wireless Sync works is the same as if you would use a wire for triggering. You 'feed' the Wireless Sync sender with a TTL signal, the module sends it through the air to the Mobita (with Sync receiver box) and records the data in the Digital channel. If you need more help, just contact me.
