Travel blanks

Trip blanks are QC samples associated with the field samples collected for VOC analysis, such as chlorinated and aromatic hydrocarbons and volatile petroleum products. Trip blanks are sometimes called travel blanks. 

In addition to the QA/QC performed by the laboratory, an independent QA/QC program administered by the data users is essentid in evalutating data quality. The "Field" QA/QC checks usually consist of travel blanks, field blanks, decontamination blanks, co-located samples, split samples, and blind standards. Split samples are most important for evaluating laboratory precision and blind standards are most important in assessing laboratory accuracy. The relative percent difference between split samples exceeded the 20 percent criteria at least once for Al, Sb, Be, Cd, Co, Cu, Fe, Mo, and Ag. Overall, few values exceeded the 20% criteria. 

If Solo did not approve of something you were doing, he would look blank for a moment and then announce that it had been revealed to him that instant, by the Beings of Light, that you shouldn t, for example, peel fruit with metal knives. The tiny minutia of existence were controlled by these hidden forces. Solo traveled with animals dogs, kittens, monkeys (he had a monkey that he supposed to be Christ incarnate). He insisted that all the animals be vegetarian, so the animals became twisted and unhealthy. As their... 

Dissimilar-thickness butt welds (tailor-welded blanks). Dissimilar-thickness welds require both a travel angle and work angle (a minimum of five axes of motion). Robots are ideal for this application. 

After the centrifuge has stopped, the segments of the mould wall are separated so that they cannot shrink onto the blank during the annealing process. The casting mould with the blank is then driven into the annealing oven and set onto the base slabs of the oven. The transport vehicle then travels back out of the oven again. 

Production of passport books and travel documents, including the personalization processes, should be undertaken in a secure, controlled environment with appropriate security measures in place to protect the premises against unauthorized access. If the personalization process is decentralized, or if personalization is carried out in a location geographically separated from where the travel document blanks are made, appropriate precautions should be taken when transporting the blank...
