First, check routine water quality. These meters are quick. They are also easy to keep in good shape.
- pH / Conductivity / DO / Turbidity meters — daily control tools.
- Residual Chlorine Analyzer — crucial for drinking water and disinfection checks.
- COD / BOD / TOC analyzers — measure organic load; therefore, they guide treatment.
Residual Chlorine Analyzer — fast disinfection monitoring.
2) Metals and Nutrients: Spectroscopy
For trace metals, use powerful optics. As a result, you get lower detection limits.
- UV-Vis Spectrophotometer — nutrients, color, and more.
- AAS / ICP-OES / ICP-MS — heavy metals at low levels.
3) Microbiology Tools
Moreover, safety matters. Keep cultures controlled and clean.
- Microbiological Incubator — stable growth conditions.
- Biosafety Cabinet — protects people and samples.
- Membrane Filtration — simple colony counts.
- PCR (optional) — rapid pathogen screens.
Microbiological Incubator — steady temperature for accurate counts.
4) Sample Prep and Safety
Next, prepare samples well. Good prep boosts accuracy. Also, it protects staff.
- Fume Hood — acid digestion and solvent work, safely.
- Muffle Furnace — ash content and residue tests.
- Digestion System / SPE / Centrifuge — cleaner extracts and lower noise.
Fume Hood — essential for corrosive and volatile tasks.
Muffle Furnace — reliable ash and gravimetric work.
5) A Simple Workflow
- Receive the sample; log it. Meanwhile, keep it cold if required.
- Screen with pH, EC, DO, and turbidity. Therefore, spot issues early.
- Prepare with filtration, digestion, or SPE, as needed.
- Analyze by UV-Vis, ICP, GC/LC, or culture tests.
- Verify with blanks, spikes, and standards. Finally, report clearly.
6) Quick Selection Tips
- Choose meters with auto-cal and stable probes; hence, less drift.
- Prefer ICP-OES for multi-element scans; however, use ICP-MS for ultra-trace.
- Pick incubators with tight temperature control; in addition, log the data.
- Always install a certified fume hood; thus, you reduce risk.
