In ex-situ measurements the catalyst is outside a proper reactor and it is in a state which is more or less different from the active state. The advantage is that we have a wide choice of temperature, pressure and gas composition. The disadvantage is that we don t really know how far the state is from the active state and we have no easy way of finding out. 

Test methods include specifications for the collection of grab samples, wastewater sludges, sludge banks, muds and composites. Advantages and disadvantages to composite sampling are reported in Standard Method 1060 B (Standard Methods,...

The principal advantage of the tilted-plate clarifier is the increased capacity per unit of plane area. Major disadvantages are an underflow solids concentration that generally is lower than in other gravity clarifiers and difficulty of cleaning when scahng or deposition occurs. The lower underflow composition is due primarily to the reduced com-... 

The most widely used techniques for surface analysis are Auger electron spectroscopy (AES), x-ray photoelectron spectroscopy (XPS), secondary ion mass spectroscopy (SIMS), Raman and infrared spectroscopy, and contact angle measurement. Some of these techniques have the ability to determine the composition of the outermost atomic layers, although each technique possesses its own special advantages and disadvantages. 

PBAs are designed explicitly to meet the needs of specific applications on the basis of their property-processing-cost performances. One polymer is incorporated into the matrix of other polymers to impart specific characteristics as per the requirement along with the appropriate compatibilizer to ensure stress transfer in between phases. The polymer blend constituents and composition must, therefore, be selected on the basis of the compensation of properties, considering the advantages and disadvantages associated with each phase. Table 12 indicates some of the components used as modifiers.
