the incorrect vial, cap or septa can contribute to problems that can decrease productivity and reproducibility. Potential Problems Caused by Using Incorrect Vial/Cap/Septum: • Loss of analyte due to evaporation • Presence of extra peaks in the chromatogram due to solvent/septum interaction • Mechanical damage to autosampler • Sample
The septum you choose for your autosampler vial can impact sample evaporation, sample security, needle bending and blockages, and instrument down time. Don’t let the complexities of septa selection slow you down.
Environmental Express. 1.5mL Polypropylene vial with septum cap for Dionex AS-50 and AS-AP Autosampler. The septum is slit for easy penetration The septum is a laminate of blue PTFE on the bottom and white silcone on the top. Compare this item.
Figure 1 illustrates a complete sample containment solution of the vial, cap, and septum, and their relationship to each other. A needle is shown piercing the cap septum and, as shown in the fi gure, the septum should be the only component that comes into contact with the needle. Autosampler needle Septum Cap Vial Sample location F igure 1.

An Aijiren Septum is Not Just a Septum White Paper The septum is one of the three main components of your sample containment system, consisting of the vial, septum, and cap. The septum is highlighted in red in Figure 1. Autosampler needle Septum Cap Vial Sample location Figure 1. A basic illustration of an Aijiren sample vial, highlighting the
The size of the container should be matched to the volume of the standard to minimize evaporation of volatile components into the headspace. Both recommended options provide 2 lines of defense against sample loss: 1) mininert valves have a PTFE valve backed up by a cylindrical red rubber septum and 2) certain vials have a capillary tube opening

Apr 1, 2016 · The diluted blood samples were ejected into 22 mL glass vials, which were immediately made airtight with a butyl rubber stopper and crimped on aluminium cap. All tubes of blood were analysed in duplicate and the mean result of six determinations (three glass and three plastic tubes) was taken as the best estimate of blood–ethanol

6 Screw Top Vials, Caps, Septa and Kits Combine the excellent autosampler handling of a crimp cap profile with the ease of a screw cap. The screw caps and precision fit septa give a secure seal with
Crimp Vials squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The septum stays seated during piercing by the autosampler needle. The crimp cap vial requires crimping tools to carry out the sealing process. For low volume settings, manual crimper tools are the

Jan 19, 2018 · 4.0 mL of the ethanol solution was added in a headspace vial (20 mL). Afterward, the headspace vial was sealed immediately by using the rubber septa (using double sealing technique and conventional single sealing technique, respectively) and a cap. The headspace vial was then transferred to the auto-headspace sampler and detected by HS-GC.
