I am looking to purchase a commercially available SECM in order to perform LEIS and/or ac SECM. Any feedback on I.e. HEKA, Bio-Logic, PAR systems would be very much appreciated. In particular I am looking for a system with high sensitivity and ability to perform analysis on biological samples.
sorry I am obviously biased but I just wanted to give you a few details. If you are already using Bio-Logic impedance analyzers (SP-300, VSP-300, VMP-300) the Bio-Logic M470 is compatible with it.
The PAR system does not offer - to my knowledge - ac-SECM techniques.
If you need more info do not hesitate to contact me.
For very sensitive measurements even from single cells I can recommend the HEKA system. The amplifier belongs to the best to date. For further details read our recent open access paper in ARS (Bozem et al. 2017). It is attached.
Do not hesitate to contact me for further information.
