AAS and ICP Single Element Standards
(TraceCERT^®and Certipur^®)

We offer a large range of single element certified reference standard solutions in various concentrations (1 mg/L, 10 mg/L, 1’000 mg/L, 10’000 mg/L) suitable for AAS, ICP-OES or ICP-MS application.

To guarantee top reliability of the values, all certified reference solutions for AAS or ICP are traceable to specified NIST or BAM SRMs. We also show the NIST-traceable density on the Certificate of Analysis for our TraceCERT^® line, together with information about the certification process, the traceability measurements, the storing behavior, the uncertainty evaluation and for the ICP product range the measured trace impurities.

Titrisol^® Concentrated Single-Element Standards for AAS

We offer an extensive range of Titrisol^® concentrated single-element standards. Simply dilute the concentrate in order to produce the desired standard solution. Titrisol^® concentrates are traceable to standard reference material from NIST and are provided in easy-to-handle plastic ampoules. Unopened Titrisol^® ampoules have a minimum expiration time of 5 years. A comprehensive batch-specific Certificate of Analysis can be downloaded from our webpage, using product and lot number.

Dilution of Titrisol^® concentrates

In preparing a dilution series, the concentrates should be diluted with the same concentration of acid as is in the standard itself. Titrisol^® concentrates should be diluted to 1l with 0.1 mol/l HCl in the first step. Alternatively, 30ml of 30% HCl can be placed in a volumetric flask and made up to 1l with distilled water. Further dilutions should then be made with distilled water.

Multi-element Standards for ICP – TraceCERT^® and Certipur^® solutions

TraceCERT^® multi-element solutions

Our TraceCERT^® multielement solutions are certified reference materials (CRMs), produced and certified under
ISO/IEC 17025 and ISO 17034. All CRMs are traceable to primary material from a National Metrology Institute (NMI).

Periodic Table Mixes
With these three multielement standard solutions, all ICP measurable elements of the periodic table are covered (excluding mercury). All components are present at a concentration of 10 mg/L.

Chemical Group Mixes
Each of these eight multielement standard solutions contains a specific group of elements. Concentrations of the analytes are 100 mg/L except for the rare elements mix where the analytes have a concentration of 50 mg/L.

TraceCERT^® mixes for special applications

Mixes acc. to ICHQ3D guidelines (pharma testing)

We offer different Inorganic elemental impurity mixes as certified reference material standard mixes with element ratios corresponding to the oral,  parenteral and inhalation elemental concentrations limits of the ICHQ3D guideline.
 

Mixes for cannabis testing

It is critical to accurately monitor levels of elemental impurities in cannabis products, both to ensure regulatory compliance – and more importantly – consumer and patient safety. Trace levels of heavy metals such as arsenic, cadmium, mercury and lead may accumulate in plant material through uptake from soil and, more commonly, may be introduced through the use of certain fertilizers.

Our heavy metal mixes are each tailored to specific US state specific regulations and offer concentrations that match the specific regulatory bodies‘ action and reporting limits.

We also offer mixes with flat concentrations.

All TraceCERT^® mixes are certified reference materials, certified according to ISO/IEC 17025 and ISO 17034.
