Which parameter shall be analyzed immediately after collection?

• A. Density
• B. Temperature
• C. Viscosity
• D. Solids

Answer: (B)

Temperature is captured first because a sample’s temperature can change quickly after collection and small changes can significantly affect how other properties behave. Recording the temperature right away gives an accurate snapshot of the sample’s state at collection and provides the necessary baseline for interpreting and correcting all other measurements to standard conditions. If you wait, the sample may warm or cool, changing density, viscosity, and even how solids settle, which can lead to misinterpretation of the results. The immediate temperature reading thus preserves the true condition of the sample and supports correct analysis and proper handling.
