MEASUREMENT PROCEDURE
• Select the Nickel LR method using the procedure described in the
Method Selection section (see page 18).
Note: For best results samples should be between 20 and 24 °C.
• Fill one graduated beaker with 25 mL of deionized water (blank)
and another one with 25 mL of sample.
• Add one packet of HI93740A‑0 Nickel Low Range Reagent A to each
beaker. Cap and swirl gently until the reagent is dissolved.
Note: If sample contains iron (Fe
3+
), it is important that all
powder is dissolved before continuing.
