  2. LIMS - VAXLIMS • Laboratory Information Management System • Information on sampling sites • Information on customers (orders) • Information on individual analytic programmes • Gives unique ID number to samples • Samples and subsamples are barcoded • Barcodes gives information to instruments and instruments returns results to VAXLIMS • Sample information etc. can be accessed from other ROVESTA departments (Holbæk, Næstved) • VAXLIMS produces final analytical reports and data for invoices

  3. Analytical selection • Waste water: • pH • Suspended solids • Biochemical and chemical oxygen demand (BOD & COD) • Nitrite, nitrate, ammonium, kjeldahl-N and total nitrogen • Ortho phosphate and total phosphorus • Chloride • Sulfate

  4. Analytical selection • Fresh- and seawater: • Suspended solids • Biochemical oxygen demand (BOD) • Nitrite, nitrate, ammonium and total nitrogen • Ortho phosphate and total phosphorus • Silicate • Chlorophyll

  5. Analytical selection • Drinking water: • pH, conductivity, oxygen • Total solids, color, turbidity • Bicarbonate • Nitrite, nitrate, ammonium • Total phosphorus • Chloride, sulfate, fluoride • Hydrogen sulfide

  6. Analytical selection • Sludge: • Total solids • Volatile solids • Total nitrogen • Nitrite+nitrate, ammonium, ortho-P (special)

  7. Quality System – DS/EN ISO 17025 • Part 1: Management requirements • Organization • Quality System • Document control • Review of requests, tenders and contracts • Subcontracting of tests and calibrations • Purchasing services and supplies • Service to clients - complaints • Control of nonconforming tests • Corrective and preventive action • Internal audits • Management reviews

  8. Quality System – DS/EN ISO 17025 • Part 2: Technical requirements • General • Personnel • Accommodation and environmental conditions • Test methods and method validation • Equipment • Measurement tracebility • Sampling • Handling of test items • Assuring the quality of test results • Reporting the results
