| Q4. How do I know whether a reference standard is available for a foreign user or not? | |
| A4: | Some of the reference standards which are restricted legally or require storage at low temperatures are not shipped overseas. In order to confirm the foreign availability, please consult the information for each item on our website or in our current catalog. |
| Storage |
| Q1: How do I determine an expiration date of a reference standard? | |
| A1: | The reference standards are not labeled with an expiration date. The suitability of the reference standard for the official use is warranted when dispatched. Thus, only sufficient quantity for immediate use should be purchased. After receipt of the reference standard, keep it immediately at a temperature specified on the label, and use it as soon as possible. Please note that PMRJ makes no warranties concerning the continued suitability of the reference standards stored for a prolonged period or previously opened. |
| Q2: How should I store a reference standard? | |
| A2: | After receipt of the reference standard, keep it immediately at a temperature specified on the label, and use it as soon as possible. For details, please see “PMRJ Reference Standards User Information”. |
| Usage |
| Q1: A certificate of analysis for a reference standard is issued? | |
| A1: | No certificate of analysis for any reference standards is issued. For details, please see “Quality Assurance”. |
| Q2: Quality specifications for a reference standard are provided? | |
| A2: | No quality specification for any reference standards is provided. |
| Q3: Where can I find information on the specific value of a loss on drying or the water content of each reference standard? | |
| A3: | The specific value of a loss on drying or the water content of a reference standard is usually not indicated. When official test or assay methods give instructions to determine a loss on drying or a water content of a reference standard, the weighed amount of the reference standard must be corrected by using the determined value. If the accompanying leaflet of a reference standard gives a specified value of a loss on drying or a water content, a weighed amount of the reference standard can be corrected by using the value given in the leaflet. |
| Q4: Where can I find information on the value of purity of each reference standard? | |
| A4: | The value of purity of a reference standard is not indicated. The reference standards are regarded as being 100.0% pure for the official use in quantitative applications, unless a specific correction factor for purity is indicated in the accompanying leaflet of a reference standard. When official test or assay methods require to dry a reference standard or to determine a loss on drying or a water content, the reference standard as dried or anhydrous basis is taken as being 100.0% pure. For reference, please see Q5. |
| Q5:What is the correction factor indicated in the accompanying leaflet of a reference standard? | |
| A5: | The reference standards are regarded as being 100.0% pure for the official use in quantitative applications (for reference, please see Q4). The reference standards, however, are not a pure substance and contain insignificant amounts of impurities. In case a reference standard contains a significant amount of impurities, a correction factor for the impurities is indicated in the accompanying leaflet, and the weighed amount of the reference standard must be corrected using the correction factor. Each lot of a reference standard, which is distinguished by ‘Control Number’, could have a different correction factor. Thus, please check the accompanying leaflet for each lot of a reference standard. |
| Q6: Please instruct me about the specific directions for usage and storage of the reference standard? | |
| A6: | Please see “PMRJ Reference Standards User Information”. |
