5 µL of the sample were injected without any dilution.
Dialysate samples were injected without any purification into an HPLC system that consists of a pump linked to an automatic injector (Agilent 1100, Palo Alto, CA, USA), a reverse-phase column (Zorbax SB C18, 3.5 lm, 150 · 4.6 mm; Agilent Technologies, Palo Alto, CA, USA) and a coulometric detector (Coulochem II; ESA Inc., Chelmsford, USA) with a 5011 analytical cell to quantify DA or 5-HT.
The guidewire of one screw was then removed and 3 mL of platelet-rich plasma, harvested in accordance with the manufacturer's recommendations (GenesisCS Component Concentrating System, EmCyte Corporation, Fort Myers, Florida, USA), was injected without an activator through the cannulated screw directly into the fracture site under image intensifier guidance.
A subsequently executed central composite design determined the largest sample plug that can be injected without compromising the separation.
Up to 4 ml could be injected without disturbing probe stability and this equates to a detection limit of 0.75 μl/L NO.
These muscles can easily be palpated in most individuals and can be injected without sophisticated techniques.
In the large muscles of the neck and back, relatively large volumes can be injected without diffusion to adjacent structures.
In contrast, our injector allows the separation voltage to be continuously applied and a variable-volume sample plug to be injected without interrupting an ongoing separation, thus enabling higher throughput and rapid optimization of the separation conditions.
Liraglutide (Novo Nordisk, Bagsværd, Denmark) is a human GLP-1 agonist, which is effective with once-daily administration, can be injected without regard to timing of meals, and is associated with weight loss and a low risk of hypoglycaemia [ 8, 10– 13].
5 μL of the samples were injected without dilution and measurement was carried out at a wavelength of 210 nm.
