2006

Sirius develops Vinotrate, a new instrument for a new market. Based on our titration and pH technology Vinotrate was designed for measuring pH and titratable acidity of wine and fruit juices. Electronics and software are completely new.

2005

Sirius Analytical Inc. opens in Piscataway, NJ. Kate Henson and Andy Latham of Sirius UK moved to the
USA to run the operation for one year. Ryan Caswell appointed in November 2005 to manage Sirius Inc.
Significant advances in CheqSol research; Chasers vs non-chasers, solubility at 37°C, evidence for changes
in crystalline form. First CheqSol paper published. Sirius corporate web site underwent another major overhaul
by Nicki Moon.

2004

Significant growth in the Analytical Service business which reflects the value of measured physicochemical
properties in ADME decision-making. Sirius sponsored a successful LogP2004 meeting in Zurich, where we
exhibited four posters concerning our latest research, including our new MDM cosolvent method, and work to
show correlations between measured PAMPA permeability and logP dodecane-water. Sirius hosted Rebeca Ruiz, a PhD student from the University of Barcelona for 6 months. Rebecca made a significant contribution towards our MDM, PAMPA and dodecane research. In April, we discovered a remarkable new way to measure intrinsic solubility of ionisable compounds. By September, we launched CheqSol software for RefinementPro2, as well as FastD-PAS, generating a substantial amount of interest. After several years of collaboration, Sirius and pION Inc. decided to go their separate ways. The latter part of the year saw Sirius preparing for the launch of Sirius Analytical Inc. on 4th January 2005. In preparation, we had our first independent exhibition booth at AAPS in Baltimore in November 2004.
