🧩 options & notes
| buffers & consumables | For higher throughput, COLO.Science can propose buffer kits, storage solutions, and electrode maintenance accessories. |
| electrode selection | Select the electrode type based on sample matrix (aqueous, viscous, high solids, etc.). Request guidance from COLO.Science. |
| calibration practice | Use fresh NIST buffers and maintain temperature consistency for best repeatability. |
🔬 practical operation notes
| topic | recommendation | note |
|---|---|---|
| calibration | Use 2–3 points for critical work; verify slope/offset trend over time | NIST buffer recognition supported; keep buffers uncontaminated |
| temperature | Use ATC when available; otherwise keep sample and buffers at similar temperature | ATC/MTC supported |
| electrode care | Rinse between samples; store electrode properly after use | Maintenance directly impacts stability and drift |
