Thermo Scientific MS Certified Vial Kits
MS Certified Vial Kits from Thermo Scientific
Use certified clean, low particle, low background vials for you high sensitivity LC-MS and GC-MS applications. They are fully lot-tested for 15 critical parameters. Pre-cleaned vial packaging protects the product integrity and high purity closures packed in air-tight re-closeable container.
Tested and certified for:
- Up to 15 critical physical characteristics affecting vial performance
- Low background by positive ESI LC-MS
- Low background by GC-MS
Thermo Scientific MS certified vial kits are tested by both LC-MS and GC-MS to ensure that there are no extractables, leachables, or residual manufacturing agents present in the vial that could generate spurious chromatographic peaks that interfere with your results. They are tested and certified for up to 15 critical physical specifications to prevent technical/performance issues. SureSTART MS certified vial kits are available in two versions: MSCERT and MSCERT+.
MSCERT kits are certified high-performance kits for use with routine mass spectrometry analyses. Recommended for low adsorption.
MSCERT+ kits are certified high-performance kits for use with mass spectrometry research applications – with an additional level of security. Kit components are pre-cleaned to provide the lowest ion content and particulate levels in the vials to protect sample integrity and guarantee that no dirt or dust from manufacturing is present to affect column lifetime and system performance. Highly recommended for direct injection analysis (DIA).
- Classed as a Performance Level 3 product for ultimate performance and sensitivity, while maintaining the highest levels of sample security and integrity
- Test results and certificate of analysis included in the kit box
- Select kits with SureStop vials and/or AVCS screw caps for effective seals, consistent data, and increased sample throughput
PTFE/Silicone is the most versatile septum material offered in various formulations to address specific applications requirements. Extractables from PTFE/Silicone septa are generally at lower levels compared to other resealable materials. PTFE/Silicone septa are formulated for different hardness (durometer) meeting requirements of various needle types. Formulations offering highly consistent performance, lowest background/blank value, and good chemical compatibility, effective sealing/resealing and low penetration force make PTFE/Silicone septa suitable for all types of chromatographic applications. A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical.
Pre-slit PTFE/Silicone Septa
Pre-slit septa are offered in many of the same formulations as for non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics. The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides chromatographic characteristics similar to that of a septum without a slit, except that the ability to withstand exposure to aggressive solvents is slightly lessened. Pre-slit septa are highly recommended for Shimadzu, Hitachi, and other autosamplers with thin gauge needles.
