Proficiency test

Since 2002, the proficiency test phytoplankton has been carried out on an international level by the LTV.

From 1.1.2025, we will no longer be able to offer ring tests to participants from countries outside the EU. We regret this decision and apologise for the inconvenience

Design of our EQAT scheme

The EQAT design is focused on the application of the Utermöhl method using the inverted microscope and consists of three components. Components 1 and 2 are methodological, focussing on the enumeration and biovolume calculation and component 3 is taxonomic in nature.

Procedure of our EQAT scheme

The EQAT scheme is divided into 9 phases, the status of which can be viewed on-line on our website. With the announcement of the EQAT scheme, the planned time schedule is communicated to the participants.

Requirements for participation, costs and evaluation

Only laboratories that have the personnel and equipment required for the EQAT proficiency test phytoplankton can participate in our scheme. Each participant in the EQAT scheme requires an individual registration.

About the organiser

The EQAT phytoplankton proficiency tests are an activity of the Landestalsperrenverwaltung des Freistaates Sachsen (LTV).

Reports

Since 2005, the evaluation of the results has been carried out in accordance with DIN 38402 – 45: 2014 using robust statistical methods.
