3. INSTRUMENTS AND EQUIPMENT
• Atomic absorption spectrometer GBC Avanta P
• Cylinders of pressurized air and acetylene (flame photometry grade)
• 10-ml volumetric flasks for the dilution of samples
• A 100-ml polypropylene volumetric flask and three 50-ml polypropylene volumetric flasks for
preparation of calibration solutions
• Pipettes with plastic tips 200–1000 μl and 1–5 ml
Note: all glassware and plastic ware should be washed using distilled water and decontaminated by
leaching with diluted nitric acid(1:10) for at least 24 hours. The recommended time of leaching is
three weeks. Then it should be rinsed thoroughly with deionised water and optionally dried in a
clean room and stored in plastic bags until use.
