1. A collection device, comprising: a membrane denuder, wherein the membrane denuder is a flexible fabric porous structure that includes at least one chemical composition that collects at least one type of gas; anda filter pack, wherein the filter pack collects aerosol particles that pass through the membrane denuder, wherein the membrane denuder is disposed on top of the filter pack so that the air flow of the gas into the device passes through the membrane denuder before contacting the filter pack an impactor disposed on the membrane denuder on the side opposite the filter pack so that the gas passes through the impactor before contacting the membrane denuder, and wherein the impactor removes large aerosol particles; and wherein the membrane denuder includes porous walls that are parallel to the air flow and perpendicular to the filter pack. 2. The collection device of claim 1, wherein the impactor includes two or more inlet orifices and exit orifice, wherein dimensions of the inlet orifices are different, and wherein the inlet orifices are used to classify different sizes of aerosol particles. 3. The collection device of claim 1, wherein the chemical composition has an affinity for one or more of the following: HCl gas, SO2 gas, HF gas, HNO3 gas, NH3 gas and volatile organic compounds. 4. The collection device of claim 1, wherein the filter pack filters out aerosols selected from the group consisting of H2SO4 and H3PO4. 5. The collection device of claim 1, wherein the chemical composition has an affinity for one or more of the following: HCl gas, SO2 gas, HF gas, HNO3 gas, NH3 gas, and volatile organic compounds, and wherein the filter pack filters out aerosols selected from the group consisting of H2SO4 and H3PO4, wherein collection of the gas and aerosols simultaneously does not result in interference between the gas and aerosol. 6. The collection device of claim 1, wherein the membrane denuder has a cross-section that is selected from a swirl pattern, grid pattern, plate pattern, polygonal pattern, multi-annular pattern, a honeycomb pattern, a repetitive “V” pattern, an accordion pattern, and a combination thereof. 7. A method of collecting aerosol particles and collecting gas, comprising: removing large particles from a gas flow using an impactor;collecting one or more gas types using a membrane denuder after removing the large particles, wherein the membrane denuder is a flexible fabric porous structure that includes at least one chemical composition that collects at least one type of gas; andcollecting one or more aerosol types using a filer pack after collecting the gas using the membrane denuder wherein the membrane denuder includes porous walls that are parallel to the air flow and perpendicular to the filter pack. 8. The method of claim 7, wherein the chemical composition has an affinity for one or more of the following: HCl gas, SO2 gas, HF gas, HNO3 gas, NH3 gas, and volatile organic compounds. 9. The method of claim 7, wherein the filter pack collects aerosols selected from the group consisting of H2SO4 and H3PO4. 10. The method of claim 7, wherein the chemical composition has an affinity for one or more of the following: HCl gas, SO2 gas, HF gas, HNO3 gas, NH3 gas, and volatile organic compounds, and wherein the filter pack collects aerosols selected from the group consisting of H2SO4 and H3PO4, wherein collection of the gas and aerosols simultaneously does not result in interference between the gas and aerosol. 11. The method of claim 7, wherein the membrane denuder has a high surface area and open porous structure that allows more efficient absorption and higher capacity of gas molecular than solid surface denuders. 12. The method of claim 7, wherein the membrane denuder does not require regeneration. 13. The method of claim 7, wherein the membrane denuder has a cross-section that is selected from a swirl pattern, grid pattern, plate pattern, polygonal pattern, multi-annular pattern, a honeycomb pattern, a repetitive “V” pattern, an accordion pattern, and a combination thereof.
