Separate a wide range of enantiomers with Hypersil™ Chiral HPLC columns, designed for separations of neutral, acidic and basic racemates in normal phase. These chiral columns can help ensure your purification needs are met by resolving racemic mixtures and potential contaminants so you can be confident in the purity of target compound. To maximize screening efficiency, these columns can be ordered in kits which contain a column in each of our chiral phases. All columns are available in analytical and preparative scale formats.

Amoxapine is a tricyclic antidepressant known to inhibit reuptake of neuronal transmitter. The drug helps in controlling agitation and anxiety along with depression.Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Application:Amoxapine may be used as a pharmaceutical reference standard for the determination of the analyte in drug dosage forms by ultraviolet-spectrophotometric method.These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

CLP Standards for ICP & ICP-MS
Our Contract Laboratory Program (CLP) standards allow you to Calibrate with Confidence®. The standards are to be used in conjunction with the Statement of Work for Inorganic Analysis; Multi-Media/Multi-Concentration Document Number ILM 05.3/ISM 01.2.

The final ICP check, performed in our own laboratories, is your stamp of assurance. We calibrate our instruments with traceable reference materials and show you the actual found value of the solution you receive, not just an ideal, calculated number as so many other standards manufacturers do. The combination of elements, concentrations and matrices listed have been diagnosed by SPEX CertiPrep for convenience of use and stability.

US EPA SOW ILM 05.3/ISM 01.2 gives specific procedures for the methods of analysis, target elements, and concentrationlevels. Standards are specified not only by the elements present and their relative concentrations, but also the order and frequency of running standards, blanks and samples. Details of these specifications may be found in the US EPA SOW ILM 05.3/ISM 01.2 in the following sections:

• Exhibit C, Inorganic Target Analyte List (TAL)
• Exhibit D, Analytical Methods
• Exhibit E, QA/QC Requirements

CLP ISM 01.2 Standards for ICP-MS
Our spike standard, CL-SPIKE-4, provides all of the analytes required for the ICP-MS and the AA spike. Add 1 ml of CL-SPIKE-4 to aqueous samples and 2 ml of CL-SPIKE-4 to solid samples prior to digestion.

CLP ILM 05.3 Standards for ICP-MS
Our spike standard, CL-SPIKE-4, provides all of the analytes required for the ICP-MS.

USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.
