We have developed a new pigment mixture, PPS-MIX-3, which contains fewer pigments distributed across the chromatogram. It is particularly useful for simpler analyses where it is not necessary to quantify all pigments present in aquatic samples.
The DHI mixed pigments can be used for controlling how well your HPLC elutes and separates the pigments, and repeated injections can be used to check the method precision and accuracy as part of the method validation.
What started in August 1995 with just a handful of pigment standards has grown into a global success story. Today, DHI Lab Products proudly offers 45+ pigment standards and support laboratories and research institutions worldwide in advancing phytoplankton monitoring and aquatic science.
Our pigment standards are essential for calibrating HPLCs used to monitor phytoplankton communities, ensuring reliable data that supports the protection of aquatic environments across the globe.
We’re happy to announce that Uriolide has been added to our pigment standard portfolio as a ready-to-use calibration standard.
DHI filtration equipment is the result of years of lab development. Our handmade, rotatable manifolds are designed for easy vacuum filtration onto 25 mm filters, with options to collect or drain filtrate. Compact and easy to use, they fit well in fume hoods and tight spaces. Each sample can be filtered independently, making the system ideal for handling multiple samples at once.
Consider having your samples analyzed by DHI. We routinely carry out many thousands of analyses each year, and DHI is accredited by The Danish Accreditation Fund to analyze phytoplankton pigments concentrations in aquatic environments.
