OpenArsenic Quick Start Guide

A brief introduction to the guide and expected users.

Gneral safety guidance including PPE, handling acids and arsenic-containing waste.

This Materials section contains lists of required and optional equipment and consummables.

Arsenic measurements follow the same basic workflow from preparing reagents to reviewing data.

Goal: Prepare a clean and organized workspace to do arsenic analysis.

How to assemble and connect hardware required for arsenic measurement using the Rodeostat potentiostat system.

OpenVoltam is the software used for potentiostat control, data collection, peak analysis, and arsenic concentration calculation.

This section describes the routine solutions needed for total arsenic measurements.

Objective: clean and re-activate the working electrode surface to ensure stable arsenic measurements.

Sampling may seem simple, but it is one of the most critical steps in ensuring that analytical results are meaningful.

Objective: quantify dissolved arsenic via stripping voltammetry and standard addition.

OpenVoltam automatically estimates peak location, baseline, and endpoints, with the user verifying the analysis.

Complete the sample run, the first standard addition, and the second standard addition.

Proper cleaning and storage of the OpenArsenic system helps maintain measurement performance.

Data analysis criteria for conditioning, measurements and standard addition steps.

This troubleshooting section includes recommended actions.

List of best practices and recommended daily routine.
