(20 [micro]L) of calibrators or sample extracts (~5 ng of thyroxine) were analyzed by LC with an isocratic mobile phase consisting of 1 mL/L acetic acid in acetonitrile-water (32:68 by volume).
ijkl] is the nitrogen recovery in the aliquot
l, at day k, using salt-to-metal catalyst ratio i, and amount of digestion mixture j; [mu] is the general constant; [R.
The prepared aliquots
were analyzed for the presence of formaldehyde and hydrogen peroxide by the guaiacol method; chlorine, hypochlorite, and neutralizers using rosolic acid (method A) and phenolphthalein (method B); Dornic acidity and alizarol (72% v/v) stability tests were also performed as described by Normative Instruction 68/MAPA (BRASIL, 2006).
Three hundred and eighteen patients were diagnosed as HIV-infected at the VCT in Cabo de Santo Agostinho, and aliquots
from 206 (64.
After transferring plasmas to aliquot
tubes and recentrifuging, the Unicel DxI results for the spiked samples all decreased to <5 mIU/mL.
All results mentioned henceforth constitute the sum of the results obtained from each aliquot
(and their replicates, if any) by experimental group, since there were no intra-group statistically significant differences (P>0.
The amount transfused with each aliquot
ranged from 5.
Initially an aliquot
of VMS is taken, to which, suppressor is added to ensure the deposition is inhibited to the furthest possible extent (brightener intercept solution).
The DNA-containing pellet was hydrolyzed in 5% trichloroacetic acid for 15 min at 90[degrees]C and resedimented, and an aliquot
of the supernatant solution was counted for radiolabel.
A fifth aliquot
with no humectant nor added water served as the control.
The sets are designed for low flow, maintenance fluid delivery mid aliquot
fluid administration where measured fluid volumes are infused via syringe.
of transformer oil from the drum of the Exxon Univolt 60 transformer oil was examined for traces of PCBs as would be evident by capillary gas chromatography with electron capture detection (GC-ECD).
