The peak height (h) is the vertical distance between a peak's apex and the baseline, and the peak area (A) colored in light blue is the area enclosed by the peak and baseline. These results will be used for the qualitative and quantitative analysis of a sample's components. ...
The measurement of the amount of a compound in a sample (concentration); meaning, how much is there?; There are two main ways to interpret a chromatogram (i.e. perform quantification): 1. determination of the peak height of a chromatographic peak as measured from the baseline; 2. determina...
Silodosin is a selective antagonist of alpha(α)-1 adrenergic receptors that binds to the α1A subtype with the highest affinity. α1-adrenergic receptors regulate smooth muscle tone in the bladder neck, prostate, and prostatic urethra: the α1A subtype accounts for approximately 75% of α1-...

To harness the benefits of condition monitoring it’s essential to invest in the right equipment. Below, we take a look at some of the most widely used CM instruments. Accelerometers for vibration analysis Vibration analysis is one of the most useful parameters used in co...
The feedback loop in Figure 3 represents this. For example, consider that there is a specification for the flow rate of an HPLC pump to be between 0.5 and 2.1 mL/min, as shown in Table 1. If a new method is implemented with a flow rate of 1.0 mL/min, there is no ...
Note that the increase is larger for C18 than for C4, indicating that more TFA is associating with the longer alkane chains. At the end of the run when acetonitrile is returned to zero, the baseline dips below its initial value, recording a deficit in the column effluent as TFA from the...
A simple gradient method was quickly developed on a 5 cm YMC Hydrosphere C(18) column that separated betamethylepoxide and alphamethylepoxide in 10 min with a resolution factor of 3.0. This high resolution provided a true baseline separation even when the concentration ratio between these two ...
