1. A method of pressurizing a fluid sample, the method comprising: disposing a fluid sampler comprising a sampling chamber, a power device, and a pressure assembly comprising an activation mechanism in a subterranean wellbore, wherein the pressure assembly comprises a pressure generating agent, wherein the power device is positioned between the sampling chamber and the pressure assembly, and wherein the pressure assembly is at or near atmospheric pressure while disposing the fluid sampler in the subterranean wellbore;obtaining a fluid sample in the sampling chamber while maintaining the pressure assembly at or near atmospheric pressure;activating, within the subterranean wellbore, the pressure generating agent with the activation mechanism in response to obtaining the fluid sample in the sampling chamber;generating a pressurized fluid having a pressure greater than atmospheric pressure within the pressure assembly in response to activating the pressure generating agent; andpressurizing the fluid sample using the pressurized fluid. 2. The method of claim 1, wherein the activating of the pressure generating agent occurs after the obtaining of the fluid sample. 3. The method of claim 1, wherein the pressure generating agent comprises a solid composition. 4. The method of claim 3, wherein the solid composition comprises an organic solid composition comprising a urea, a multi-component system, or any combination thereof. 5. The method of claim 3, wherein the solid composition comprises a fuel and an oxidizer. 6. The method of claim 5, wherein the fuel comprises at least one composition selected from the group consisting of: a tetrazine, an azide, an azole, a triazole, a tetrazole, an oxadiazole, a guanidine, an azodicarbon amide, a hydrazine, an ammine complex, a nitrocellulose, any derivative thereof, any salt thereof, and any combination thereof. 7. The method of claim 5, wherein the oxidizer comprises at least one composition selected from the group consisting of: a chlorate, a perchlorate, an oxide, a nitrite, a nitrate, a peroxide, a hydroxide, a hydride, a dicyanamide compound, any derivative thereof, any salt thereof, and any combination thereof. 8. The method of claim 3, wherein the solid composition further comprises at least one additive selected from the group consisting of: a binder, a coolant, a slag forming agent, and a processing agent. 9. The method of claim 1, wherein the activation mechanism comprises a percussion cap, or an electrically initiated activation mechanism. 10. The method of claim 1, wherein the activation mechanism comprises an electrically initiated sparking device or an electrically initiated heat source. 11. The method of claim 1, wherein the power device is configured to provide an impulse for activating the activation mechanism, wherein the power device is separate from the pressure assembly and the activation mechanism. 12. The method of claim 1, wherein the pressure generating agent comprises a first component and a second component, wherein the first component is selected from the group consisting of: a carbonate and a bicarbonate, and wherein the second component comprises an acid. 13. The method of claim 1, wherein the pressurized fluid has a pressure of at least about 1,000 pounds per square inch. 14. A method of generating pressure for use in pressurizing a fluid sample within a subterranean wellbore, the method comprising: positioning a sampling chamber, a power device, and a pressure assembly comprising an activation mechanism and a pressure generating agent within a subterranean wellbore, wherein the pressure assembly is at a first pressure when the pressure assembly is positioned in the subterranean wellbore, and wherein the power device is positioned between the sampling chamber and the pressure assembly;obtaining a fluid sample in the sampling chamber;activating, within the subterranean wellbore, the pressure generating agent with the activation mechanism to generate a pressurized fluid in response to obtaining the fluid sample in the sample chamber, wherein the pressurized fluid is at a second pressure, and wherein the second pressure is greater than the first pressure; andusing the pressurized fluid to pressurize the fluid sample in the sampling chamber in response to the activating. 15. The method of claim 14, wherein the pressure generating agent comprises a solid composition. 16. The method of claim 15, wherein the solid composition comprises at least one composition selected from the group consisting of: a tetrazine, azide, an azole, a triazole, a tetrazole, an oxadiazole, a guanidine, an azodicarbon amide, a hydrazine, an ammine complex, a nitrocellulose, any derivative thereof, any salt thereof, and any combination thereof. 17. The method of claim 14, wherein the power device is operably associated with the fluid sampler, wherein the power device is separate from the pressure assembly and the activation mechanism. 18. The method of claim 17, further comprising translating the power device into engagement with the activation mechanism, and providing an impulse for activating the activation mechanism based on the engagement of the power device with the activation mechanism. 19. The method of claim 18, wherein the impulse is a mechanical impulse or an electrical impulse. 20. The method of claim 18, wherein activating the pressure generating agent to generate the pressurized fluid occurs in response to the impulse.
