In this episode, the Inorganic Ventures team continues their overview of SEAL-compatible Discrete Analyzer Reagents—this time focusing on four essential nutrient and anion methods: chloride, sulfate, phosphate, and ammonia.

Ashley Jones and Liv Forbes break down the key reactions behind each method, including:

• The iron thiocyanate reaction for chloride
• Turbidimetric analysis of sulfate via barium sulfate formation
• The molybdenum blue reaction for phosphate
• A safer variant of the Berthelot reaction for ammonia

They also share storage tips, instrument compatibility notes, and how to adapt these reagents for non-SEAL platforms.
