Performance improvement cycle expectations

Today s predominance of the gas phase sequencer for sequence analysis is partly due to the advancement of PTH-amino acid analysis on HPLC, in which the analysis takes only 10 min to complete using reversed-phase column.70-72 Thus, a gas phase sequencer with an on-line PTH-analyzer can perform a single Edman degradation cycle within one hour. With the use of a microbore column and a data station which handles various data manipulations, a few pmol of PTH-amino acid can be quantitatively analyzed. Although the minimum detection level of amino acid derivatives has improved significantly in the last 10 years (103-104-fold enhancement), further improvement is expected with the use of a fluorescent compound, i.e., fluorescein isothiocyanate (FITC), and the laser detection technique. 

Recycling is an important determinant of environmental performance [40-46,53]. To the extent that nanocomposites can be recycled a number of times as product, material, or constituent substances, with limited inputs into the recycling process, the environmental performance per cycle of usage might improve. Also, incineration of nanocomposites with energy recovery may be expected to do better environmentally than landfilling [42]. 

Both CMOS and bipolar devices encapsulated with the new transfer molding compositions performed well under thermal cycling between -65°C and + 150°C and also under accelerated life testing at 145°C, 85% RH and 18V bias. Further optimization of this type of molding composition is expected to improve its performance as a protective material for integrated circuitry.
