1. PURPOSE AND SCOPE

This Standard Operating Procedure (SOP) defines the systematic methodology for the conduct and reporting of Total Suspended Solids (TSS) Analysis. This procedure is applicable to all [___________] (the "Department/Facility") operations and personnel responsible for environmental compliance, laboratory testing, and quality assurance.

2. PROCEDURAL OBJECTIVES

The objective of this SOP is to ensure the accuracy, reproducibility, and legal defensibility of all analytical data generated. Adherence to these protocols is mandatory for compliance with [___________] (e.g., EPA/ISO/Local Regulatory) standards.

3. PRE-ANALYTICAL PREPARATION

3.1 Equipment Verification

Before initiating the analysis, the technician must verify that the following equipment is calibrated and in proper working order:

• Analytical Balance (Minimum Sensitivity: [___________])
• Drying Oven (Set to [___________]°C)
• Desiccator (Verified seal: [___________])
• Vacuum Filtration Apparatus

3.2 Sample Collection and Handling

Samples must be collected in accordance with the [___________] Sampling Protocol. Samples shall be stored at [___________]°C and analyzed within [___________] hours of collection.

4. ANALYTICAL METHODOLOGY

4.1 Filter Preparation

1. Place the filter paper on the filtration apparatus, rough side up.
2. Apply vacuum and wash with three successive [___________] mL volumes of reagent-grade water.
3. Dry the filter in the oven at [___________]°C for [___________] minutes.
4. Cool in the desiccator to room temperature and record initial weight: [___________] mg.

4.2 Sample Processing

1. Thoroughly agitate the sample container to ensure homogeneity.
2. Filter a measured volume ([___________] mL) through the prepared glass fiber filter.
3. Wash the filter with [___________] mL of reagent-grade water to remove dissolved solids.
4. Dry the filter and residue at [___________]°C for [___________] hours.
5. Cool in the desiccator to room temperature and record final weight: [___________] mg.

5. CALCULATIONS

Total Suspended Solids shall be calculated using the following formula:

$$TSS (mg/L) = \frac{(A - B) \times 1,000,000}{\text{Sample Volume (mL)}}$$

• A: Weight of filter + dried residue ([___________] mg)
• B: Weight of filter ([___________] mg)

6. QUALITY CONTROL AND DATA INTEGRITY

• Duplicates: A duplicate analysis shall be performed at a frequency of [___________].
• Blanks: Reagent blanks must be analyzed every [___________] samples.
• Reporting: All raw data must be recorded in the official Laboratory Information Management System (LIMS) or logbook [___________].

7. DEVIATION AND NON-CONFORMANCE

Any deviation from this SOP must be documented in the Non-Conformance Report (NCR) #[___________] and signed by the Quality Assurance Manager.
