# QAGTM 820 Quantitative Aerosol Generator (QAG)

Key Features

• 

### Quantitative aerosol Traceable to NIST Standards

• 

### Simultaneous for one or more elements

• 

### Wide range: ng/dscm to mg/dscm

• 

### Automatic mass loss reporting

• 

### Single operator with minimal input requirements

The QAGTM creates an aerosol of know concentration by ultrasonically nebulizing a solution. The resulting droplets are carried out of generation area to a drying chamber where they are dried to salt particles. Depending on the application for the salt particles the size can be varied to a number mean between 0.1 and 2 μm in diameter. The aerosol exiting the drying chamber contains known concentrations of analyte elements calculated from the QAG’s input parameters. This reference aerosol produced by the QAG is process traceable to NIST standards and can be used to challenge and evaluate the accuracy, precision and linearity of measurement methods such as the Xact series monitors during certification and RATA. 

## Approved by US EPA for Multi-Metal CEMS Audits and Certifications

Stability has been demonstrated through repeated use in the laboratory and in the field for over five years. The QAG can be operated by one user with mi nimal parameter inputs and control. The QAG may also be potentially applicable to other inorganic analytes including most hazard ous elements in stack and fugitive emissions as well as those present in the ambient environment.
This instrument is the first quantit ative aerosol generator to be approved by EPA for evaluating, validating and certifying continuous multi-metals CEMS used for complia nce demonstration. The QAG greatly simplifies the certification and auditing of multi-meta l CEMS and eliminates the need to compar e multi-metal CEMS results to less precise and less accurate traditional multi-metal re ference methods such as EPA Reference Method 29.
