  1. 1. ANALYTICAL SERVICES Fast, reliable PhysChem CRO services from Sirius Analytical
  2. 2. Ionisation: pKa Aggregation: Surface Activity Our state of the art instrumentation delivers pKa values, We can measure Surface Tension, Critical Micelle Distribution of Species plots, Buffer Capacity profile, ionic Concentrations, Total Surface Area and Air/Water partition strength profiles and more using minimal sample co-efficient. quantities. Toxicity: Phospholipidosis Lipophilicity: logP & logD We have the facility to screen compounds for the potential We have a number of techniques for measuring lipophilicity to induce phospholipidosis. of compounds, including potentiometry, shake-flask and HPLC-based methods that allow us to measure both ionisable and neutral compounds. In combination with Screening Services: pKa, logD, PAMPA ionisation data we provide full pH vs. logD profiles. For fast but dependable PhysChem data in bulk we offer high-throughput screening services. Solubility: Kinetic, Equilibrium, Intrinsic, pH vs. Solubility profiles Expertise: Our advanced solubility capabilities include measurement of both kinetic and thermodynamic solubilities, as well as The scientists that run our analytical service are highly supersaturation determination, excipient profiling and experienced in the measurement of physchem properties. measurements in bio-relevant media. This information can In addition to receiving the requested results, our clients bring great insights into the precipitation characteristics of also receive our expert assessment of the compound a drug, and can help greatly in the understanding of physchem properties and the correlation between the absorption properties and the effects of formulations. results obtained and any structural information provided. This enables all our clients to benefit from our data interpretation, not just Dissolution: Simulated Intestinal Fluids simple numbers. Using in-situ UV tools we can monitor the release of drug into solution over time. Our capabilities include real-time pH control in the vessel, and measurement in the presence of excipients and bio-relevant buffer media including FaSSIF & FeSSIF simulated intestinal fluids. Solid State: XRPD, TGA, DSC, Raman We partner with a leading solid-state expert who can apply cutting edge solid state techniques to provide additional evaluation of crystals obtained from any of our solution chemistry assays.
  3. 3. Confidentiality and Security assured We sign a non-disclosure agreement with all customers before accepting samples for analysis. As soon as we receive your samples and log them in, we will place them in a locked safe, together with all confidential documents. The safe contains an array of lockable drawers. Each drawer contains samples from only one client.
