Sorting Problems with EPICS Altra

Hi flowers!

I have a problem concerning setting the delay during the setup routine on my
EPICs Altra Sorter.

The current settings are:
- 70µm flow cell tip
- 32 psi
-Frequ.: around 65.0 kHz
-Drive: ca. 18-24 %
- Delay: 43-44

Using the matrix mode I try to sort 20 beads in one drop.
However, here comes my problem: The beads are split in at least three drops
with a maximum of 8-10 in one drop and 3-5 in both other drops. In
addition, these drops spray. This observation is very consistent and
reproducable.
Changing frequency, drive, room temperature etc. did not solve it.

Can anyone help me?

Thank you!

Matthias Heil
