Process Assurance
According to IEEE, quality assurance is defined as "a planned and systematic pattern of all actions necessary to provide adequate confidence that an item or product conforms to established technical requirements." Quality assurance (QA) can be broken down into two main areas: product assurance and process assurance

Métodos de decomposição por via seca ou úmida
Dry Ashing is usually performed by placing the sample in an open inert vessel and destroying the combustible (organic) portion of the sample by thermal decomposition using a muffle furnace. Typical ashing temperatures are 450 to 550 °C. Magnesium nitrate is commonly used as an ashing aid. Charring the sample prior to muffling is preferred. Charring is accomplished using an open flame.
Wet Ashing is treatment of the sample with a moderate amount of sulfuric acid before charring. Charring is performed using an open flame. Liquid samples tend to foam. After the excess sulfuric acid is driven off, the sample is muffled as above.

Discussion
Wet Ashing:
Advantages: Little loss of volatile minerals occurs because of the lower temperatures used, more rapid than dry ashing.
Disadvantages: Labor intensive, low sample throughput. Typically, a digestion takes from 10 minutes to a few hours at temperatures of about 350oC-450oC. The resulting solution can then be analyzed for species of interest.

Dry Ashing: Performed by placing the sample in an open inert vessel and destroying the combustible (organic) portion of the sample by thermal decomposition using a muffle furnace. Ashing temperatures usually range from 450 to 550oC. Magnesium nitrate is a common ashing aid. Usually, the sample is charred prior to muffling. Charring is accomplished using an open flame (crucibles/clay triangles/Bunsen and/or Meeker burners under a hood).
Wet Ashing: Samples are treated with a small to moderate amount of sulfuric acid prior to charring. The charring is performed using an open flame (crucibles/clay triangles/Bunsen and/or Meeker burners under a hood).. Liquid samples have a tendancy to foam. After the excess sulfuric acid is driven off, the sample is muffled from 450 to 550oC.
For example: Charring and ashing can form metal oxides. The objective is to keep the temperature on the low side (approx. 450oC). Metal oxides can be very difficult to dissolve.
