Sample Pooling Concentration Calculator
Plan an equal-volume pool from multiple source samples, account for processing loss, compare the recovered concentration with the target, and identify any dilution volume or concentration gap.

Recovered pool volume-
Recovered pool concentration-
Volume supportable at target concentration-

Decision view
Source aliquots to recovered sample pool
Source aliquots to recovered sample poolEqual-volume source aliquots are combined, handling loss is separated, and the recovered pool is checked against the entered concentration target.
Exact scenario comparisonAliquot volume per sample (uL) changes while all other entered assumptions remain constant.
| Aliquot volume per sample (uL) | Gross pooled aliquot volume | Gross relative analyte mass | Recovered relative analyte mass | Recovered pool volume | Recovered pool concentration | Volume supportable at target concentration | Diluent volume available to reach target | Target concentration minus recovered concentration | Total source material retained | Modeled analyte recovery |

How to use Sample Pooling Concentration Calculator
- Confirm every concentration uses the same unit.
- Choose an aliquot that leaves enough source material for retesting.
- Record the final pool volume after mixing rather than assuming perfect recovery.
Calculator guide
Understanding Sample Pooling Concentration Calculator
A pooled laboratory sample must preserve the intended concentration, volume, and representation of every source sample without exhausting the retained material.
Calculation method
How the calculation works
Combine equal-volume source aliquots, retain an explicit archive volume, apply handling loss, and reconcile recovered analyte mass and pool volume with the entered concentration target. The calculator multiplies source count by the aliquot volume, converts average source concentration into total analyte mass, applies the entered recovery loss, and reconciles recovered mass with the target pool concentration.

Worked situations
Practical examples
- A sequencing library pool can start with equal-volume aliquots before a later molarity-normalized refinement.
- A composite environmental sample may reserve a separate archive aliquot.
- A low recovered concentration can require concentration rather than dilution.
Better inputs
Useful tips
- Mix each source before aliquoting.
- Use low-retention consumables when adsorption matters.
- Document excluded samples and actual recovered volume.
Before relying on the result
Limitations and common mistakes
- Average source concentration hides sample-to-sample variation.
- Pipetting error, adsorption, degradation, matrix effects, and unequal recovery are not predicted.
- This arithmetic plan is not a validated laboratory protocol.
Reference
Key terms
- Aliquot
- A measured portion removed from a source sample.
- Pool
- A combined preparation containing material from multiple sources.
- Recovery
- The share of analyte retained after handling losses.
Important note
Calculated from the entered values using the displayed biological or statistical model. Study design, sampling, measurement quality, and biological variation affect interpretation.
Frequently asked questions
Does equal-volume pooling normalize samples?
No. Equal contribution requires concentration-aware aliquots.
Can the calculator recommend concentration hardware?
No; select a validated method for the material.
Should controls enter the pool?
Only when the assay design explicitly requires them.
