Aug 1, 2019 · autosamplers operate with the sampling needle as part of. the sample loop. It has two major instrumental setups—. with the metering device as part of the high-pressure flow. path (Figure 4a) or
Click image to enlarge. All autosamplers aspirate a sample from a vial or well plate. Differences arise in sample placement inside the sample loop and the relationship of the needle to the mobile phase flow path. There are two main autosampler operating principles: pushed/pulled-loop and split-loop. In pushed-loop and pulled-loop autosamplers
Jul 1, 2016 · In the filled-loop mode, the rotor is placed in the load position, as shown in Figure 1a. In this configuration, the pump output is connected directly to the column through one of the rotor passages; the sample loop connects the sample inlet to waste. Sample is introduced manually from a syringe or in an autosampler from an automated syringe.
Automation is no longer just going from sample to sample for analysis. From eliminating process order and transcription errors of sample information to complex cleaning and environmental control and protection for analysis, our autosamplers are designed to assist in every way for flexible workflows and efficient analysis.
Carryover has many sources, but the most common source of carryover is related to the autosampler and occurs when sample components adhere to or absorb onto the outside of the needle. A key attribute of modern autosamplers is the ability to effectivity remove sample from all active surfaces of the autosampler.
displacement supply to prevent sample carryover • Minimal y-axis assembly movement over samples • One central vial rack for 24, 48, 96 positions; also option for Bel -Art style half rack (30 or 42 position) • PFA standard and PFA or PP sample vials • Integrated autosampler cover (prevent sample contamination) with front door (easy access)

Sample/Standard Carryover. I am running GC (FID detector) alongside G1888 headspace. I had noticed 4 of my later eluting peaks got increasingly worse in terms of shape and reproducibility. After running blanks (no injection and also blank vials), it seemed like the cause of this turns out to be carryover.

flush cycle and minimizing sample carryover (< 0.1%). Flexibility The ASI-100/ASI-100T allows easy loading of samples without the extra step of removing the sample carousel. The removable carousel is divided into three 120˚ sectors; each segment is interchangeable to accept eight different vials (Table 1). All three sectors can be configured
vials and closures from microsampling to headspace to match popular application requirements. Vial choices include: Crimp Top, Snap Top, and Screw top vials with a selection of closures. Refer to the Autosampler Compatibility Table on pages 10-11 to determine which vials, closures and inserts will work on your specific autosampler unit.
