I OPERATE A FACSTAR+ AND ON OCCASIONS I RUN SUPER TRASH SPECIMANS. OF
COURSE
WE FILTER [SOMETIMES 2X], AND WE
WILL USE ANTI-COAGULANT OF CHOICE. WHAT I FOUND HELPS ME THE MOST IS AS FOLLOWS:
1. LOWER YOUR THRESHOLD TO 20. THIS GIVES UOU A REALISTIC EVENT COUNT
OF WHAT
IS PASSING THROUGH YOUR 70
MICRON APERATURE. [COULD YOU USE 100u ?]
2. LOWER YOUR EVENTS /SEC. TO APOX. 2K.
3. BACK FLUSH [SAMPLE CHANGE] EVERY 30-45 MIN..
4. IF THINGS GET REALLY BAD DON'T BE SQUIMISH ABOUT USING 20% CLOROX FOR
10 MIN
FOLLOW WITH A D.WATER RINSE.
I REALIZE THIS DOSE NOTHING FOR THE THE DEUL PLOT VISUAL PROBLEM. HERE
YOU MAY
WANT TO MAKE A SINGLE FSC
HISTOGRAM UNGATED.
GOOD LUCK
