Notice of Change
Dear Loyal Customer:

Abel Industries, Inc, has changed its name to General Separation Technologies, Inc., while remaining at the
same location, to better reflect our strength in chromatographic separation technologies.  As the result, the
AbelBonded (AB) GC column brand name has been changed to General separation Bonded Phase (GsBP).
All GsBP columns have been tested with the same quality specifications as AB columns have been.

During the transition period, we are using both AB and GsBP brand names for our GC column products. We
appreciate you understanding these business changes, and you supporting our business.

Sincerely,

Zhenghua “Zack” Ji, PhD
