Advanced calculations support blanks, dilution, replicates, and units. Instant results appear above with visual plots. Built for accurate wastewater, environmental, and laboratory reporting tasks.
Leave unused replicates blank. The calculator accepts one to three complete replicate sets.
Wdried is the dried filter plus solids mass, Wtare is the clean filter mass, B is blank correction, DF is dilution factor, and V is sample volume in mL.
This page converts all mass inputs to milligrams and all volume inputs to milliliters before calculation. When multiple replicates are entered, the final reported value is the arithmetic mean of replicate TSS results.
Example assumptions: mass unit mg, volume unit mL, blank correction 0.20 mg, dilution factor 2.00.
| Replicate | Tare (mg) | Dried (mg) | Volume (mL) | Corrected Residue (mg) | TSS (mg/L) |
|---|---|---|---|---|---|
| Replicate 1 | 145.20 | 146.55 | 250.00 | 1.15 | 9.20 |
| Replicate 2 | 145.10 | 146.80 | 250.00 | 1.50 | 12.00 |
| Replicate 3 | 145.30 | 146.60 | 250.00 | 1.10 | 8.80 |

Total suspended solids measure particles retained on a pre-weighed filter after drying. It represents suspended matter in water, wastewater, runoff, and process samples.
Blank correction removes background mass from filters, reagents, or handling. It helps prevent overestimation when the residue added by the sample is very small.
Dilution factor adjusts the result when the original sample was diluted before filtration. The measured residue is multiplied to represent the concentration in the undiluted sample.
Yes. One complete replicate produces a valid TSS value. Multiple replicates are better because they provide an average, standard deviation, and precision review.
The result becomes physically invalid. This usually indicates entry mistakes, unstable drying, balance error, or an incorrect blank correction value.
The calculator accepts mass in milligrams or grams and volume in milliliters or liters. All values are converted internally before calculation.
Milligrams per liter is the common reporting unit for water quality solids. It is easy to compare across samples, standards, reports, and treatment processes.
High variation can suggest inconsistent filtration, incomplete drying, contamination, non-homogeneous samples, or volume measurement errors. Review technique before reporting final data.
