Vitar worked as an "apparatus operator," records show.
Six tests were performed by each operator on each apparatus.
Setting the target nanospray current to a predefined value and letting the apparatus reach the target without operator intervention enabled the acquisition of viable data from solutions containing up to 2.5 M ammonium acetate, which are ordinarily difficult by traditional manual tuning.
To evaluate the reproducibility of the assays (ISO 3534 1 norm 1993), independent tests were performed with the same protocol, using the same samples, in two different laboratories, by two different operators using different apparatus (Bio-Rad iQ5 and ABI 7300).
The piece in question is a rotating apparatus, or turntable, that connects the operator's cab and the boom to the crane tower.
Fundamental modes of graphene layer at the Г (D6h), K (D3h), and M (D2h) points of the Brillouin zone were identified by using the apparatus of the quantum-mechanical projection operator.
To evaluate the repeatability of the assay, independent tests were performed with the same protocol, with the same samples, by the same operator using the same apparatus within a short interval of time (ISO 3534 1 norm 1993).
The repeatability of the assay can be evaluated thanks to the independent tests performed, i.e. with the same protocol, with the same samples, by the same operator using the same apparatus within a short interval of time [ 41].
To evaluate the reproducibility of the assays (Anonymous 1993), independent tests were performed with the same protocol, using the same eight samples, in two different laboratories by two different operators using two different apparatus (ABI7300 and Bio-Rad iQ5).
