Claims17
A filter for analyzing gas comprising:
- a polycarbonate membrane having a pore size of about 2 micrometers or less, secured to a support.
A filter for analyzing gas comprising:
- a supported polycarbonate membrane having a pore size of about 2 micrometers or less, wherein the support comprises an annular support.
A filter for analyzing gas comprising:
- a polycarbonate membrane having a pore size of about 1 micrometer or less;
- and
- a support secured to the membrane.
A filter for analyzing gas comprising:
- a polycarbonate membrane having a pore size of about 1 micrometer or less;
- and
- an integral support.
The filter of any preceding claim, wherein the support is thermally bonded to the membrane.
A device for analyzing gas comprising:
- a housing having at least one inlet and at least one outlet and defining a gas flow path between the inlet and the outlet;
- a filter disposed in the housing across the gas flow path, wherein the filter comprises the filter of any preceding claim.
A method for analyzing gas comprising:
- passing gas including particulate matter through a filter comprising a supported polycarbonate membrane having a pore size of about 2 micrometers or less;
- and
- determining the particulate matter collected by the filter.
A non-gravimetric method for analyzing gas comprising:
- passing gas including particulate matter through a filter comprising an integrally supported polycarbonate membrane having a pore size of about 1 micrometers or less:
- and
- determining the particulate matter collected by the filter.
A method for analyzing gas comprising:
- passing gas including particulate matter through a filter comprising an integrally supported polycarbonate membrane having a pore size of about 1 micrometers or less:
- and
- determining the particulate matter collected by the filter.
