Dr. Petra Werner
Do you need a diatomist? You have come to the right place.
I have years of experience using benthic and planktonic diatoms as bio-indicators (References, Curriculum Vitae), e.g. to implement the European Water Framework Directive and in paleolimnology (Publications).
I would love to offer you a quotation, if you need someone to
- prepare your samples,
- identify and count your diatoms and
- to analyse and report the results (Contact).
Equipment:
For diatom identification I use the microscope “Axio Scope.A1” from Zeiss with a 100x magnifying objective „Plan-Apochromat“ (numerical aperture of 1.4), differential interference contrast (DIC), the camera “AxioCam ICm1” and the following identification literature:
