1. A collection device, comprising: an impactor, wherein the impactor removes large aerosol particles;a filter pack, wherein the filter pack collects aerosol particles that pass through the impactor, wherein the impactor is disposed on top of the filter pack so that the air flow of the gas into the device passes through the impactor before contacting the filter pack; anda porous denuder, wherein the porous denuder is a denuder with its wall constructed of a porous material which includes at least one chemical composition that collects at least one type of gas, wherein the porous denuder includes porous walls that are parallel to the air flow and perpendicular to the filter pack,wherein the porous denuder is disposed on the filter pack on the side opposite the impactor so that the gas passes through the filter pack before contacting the porous denuder wherein the porous denuder is a flexible fabric porous denuder. 2. The collection device of claim 1, wherein the porous denuder has an accordion shaped cross-section. 3. The collection device of claim 1, wherein each of the porous denuder, the filter pack, and the impactor, have a rectangular cross-section. 4. 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. 5. The collection device of claim 1, wherein the porous denuder includes open porous walls that are parallel to the air flow and perpendicular to the filter pack. 6. 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. 7. The collection device of claim 1, wherein the filter pack filters out aerosols selected from the group consisting of H2SO4 and H3PO4. 8. 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. 9. The collection device of claim 1, wherein the porous 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. 10. The collection device of claim 1, wherein the impactor includes one or more inlets to the collection device and one or more exits at a bottom of the impactor. 11. The collection device of claim 10, wherein the bottom of the impactor directly below an entrance of the impactor is an aerosol particle impaction plate that collects large aerosol particles. 12. A method of collecting aerosol particles and collecting gas, comprising: removing large particles from a gas flow using an impactor;collecting one or more aerosol types using a filer pack after collecting large particles by the impactor; andcollecting one or more gas types using a porous denuder after removing particles, wherein the porous denuder is a denuder with its wall constructed of a porous material which includes at least one chemical composition that collects at least one type of gas, wherein the porous denuder includes porous walls that are parallel to the air flow and perpendicular to the filter pack, wherein the porous denuder isdisposed on the filter pack on the side opposite the impactor so that the gas passes through the filter pack before contacting the porous denuder; and wherein the porous denuder is a fexible fabric porous denuder. 13. The method of claim 12, 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. 14. The method of claim 12, wherein the filter pack collects aerosols selected from the group consisting of H2SO4 and H3PO4. 15. The method of claim 12, 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. 16. The method of claim 12, wherein the porous 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. 17. The method of claim 12, wherein the porous denuder does not require regeneration. 18. The method of claim 12, wherein the porous 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. 19. The method of claim 12, wherein the impactor includes one or more inlets to the collection device and one or more exits at a bottom of the impactor. 20. The method of claim 19, wherein the bottom of the impactor directly below an entrance of the impactor is an aerosol particle impaction plate that collects large aerosol particles.
