o The sample should be prepared in running buffer to minimize RI peak due to sample solvent. This is particularly important for samples that run near the solvent peak. • Know the UV extinction coefficient (in ml/mg•cm) and concentration (in mg/ml) of your protein. o Concentration should be accurately measured to assess column recovery.
In addition, direct analysis utilizing a sample loop is used for sub-sampling from polytetrafluoroethylene (PTFE) bags (Method 0040). Method 5000 provides more general information on the selection of the appropriate introduction method. 1.3 This method can be used to quantitate most volatile organic compounds that have boiling points below 200 EC.

and sample preparation process begins at the point of collection and extends to the measurement step. The proper collection of sample during the sampling process (called primary sampling) is the initial contact with the sample and it is imperative that this sample represents the entire lot being investigated.

Navid Jubaer The offset is from the default position (approx. 2 mm from the bottom of the vial). A negative offset will result in the needle being lower in the vial when the sample is drawn. A
These one-piece microvials have a very low residual volume due to a specially shaped deep and narrow inner reservoir which collects the liquid in the base so compatible autosamplers can collect all but 1-2 microliters of sample while having a total sample volume of 1.2mL.
need to withdraw large volumes from 2 mL vials. For example, transferring 0.5 mL solvent or sample from one vial to another can create a partial vacuum in the source vial. This results in poor reproducibility because the degree of vacuum varies from vial to vial and the amount of liquid actually transferred also varies. One way to elim-
Aijiren's 2 mL screw top vials are constructed from Type 1 borosilicate glass, with low metal content, to protect your sample from destabilizing or leaching. Our 2 mL glass vials are available in both amber and clear versions. The associated 9 mm vial screw cap comes with your choice of septa constructed from either PTFE/silicone, PTFE/silicone
As an example, for the commonly used UHPLC column dimension of 50 x 2.1 mm which has 173 µL total volume, and a void volume of ~120 µL (considering a factor of 0.7 for a packing with fully porous particles) the injected volume should be in the range of 1.2 and 2.4 µL (when sample concentration is ~1 µg/µL), to limit band broadening and
