A New Era in Canister Analysis Has Arrived

Entech has been developing new technology to improve canister monitoring for over three decades, and our latest announcement may be the greatest single advancement in canister analysis to  date. The SkyCan™ Autosampler represents a giant leap forward in bringing today’s canister laboratory inline with other GCMS laboratories, by moving canister samples above the GCMS, maximally  close to the GC or sample preconcentrator prior to analysis. The SkyCan™ Autosampler improves system integrity by removing the sample-to-sample variability present in multi-inlet  rotary stream select valve autosamplers. Such autosamplers are further compromised by the long residence times of samples in each line, making it difficult to reduce background levels. With the  recent reduction of allowable system background levels (e.g. EPA Method TO-15A), autosamplers that rely on rotary valves may no longer be capable of consistently achieving the extremely low  blank levels required to provide sample analysis at parts per trillion detection limits. Can you imagine having to demonstrate blank levels for each individual line on all your multi-inlet  autosamplers, every day? The SkyCan simplifies the process, as running one standard system blank is all that’s needed given that the SkyCan is equipped with only one inlet! How easy is that? This  eliminates the need to make assumptions about system hygiene, by directly proving it, daily, or more frequently if needed. With the SkyCan you enjoy all of the advantages of a robotic system: a single inlet, short sample  exposure times, vacuum cleaning between samples, reliable blank levels, connection to cans only at the time of sampling, exceptional resistance to contamination, and no risk of cross-contamination  caused by leaky stream select valve rotors, among other advantages. We urge you to free yourselves from the burden of cluttered lab spaces, reclaim your valuable bench space, improve shipping and  can cleaning efficiency – all with just one step… Take to the Sky!

Next Generation Features to Put your Lab Ahead of the Competition

The features of the SkyCanTM are truly remarkable:
  • No bench or floor space required for samples. All are placed above the GCMS, the preconcentrator, and the data system.

  • Fully automated rail system with magnetic sensing of tray and canister sampling platform positions.

  • Trays are available to handle all Entech canister sizes 2.5L and smaller, as well as 500cc and 1L Bottle-Vacs

  • Analyze 36 of the new Entech 2.5L ambient sampling canisters, that provide plenty of sample to reach today’s expected detect limits while reducing shipping and storage costs.

  • Heated transfer line length to preconcentrator only 2' long to reduce surface interactions, improving run to run consistency.

  • Inlet transfer line is vacuum cleaned immediately after exposure to the sample.

  • SkyScreenTM option uses a completely different flow path to perform high throughput screening with zero chance of carryover.

  • Fully integrated into Entech's latest preconcentrator control software

The Ultimate TO-15A Solution: SkyCan + 2.5L Silonite-XL Canister

With the latest introduction of the US EPA Method TO-15A, labs must now prove both cleanliness down to 0.02 PPB, and sub-PPB level stability in EVERY canister, for 2 weeks to 30 days depending  on quoted holding times by the lab. Given that numerous 6L canisters have been heavily utilized over the past 35 years, it is highly probable that a significant portion of them will not satisfy the  new, rigorous requirements. What better time to look at changing to a new canister geometry that is optimized for today, not 35 years ago when TO-14 first appeared. The new Entech 2.5L Silonite- XL Canister is just such a technology, as it takes advantage of improved GCMS sensitivity which has increased over 100x in the past 35 years. With the 250mL sample size recommended in Method  TO-15A, a 6L sample container is no longer needed. The more compact Entech 2.5L Silonite-XL canister provides plenty of sample for multiple analyses, occupies less space in the lab, and up to nine can  ship in the same box used to ship just four 6L canisters.

SkyCan 75” - SK75

With an impressive span of 75”, the SK75 provides the ultimate solution for maximum unattended TO-15/TO-15A analysis. Analyze 36 of the new Entech 2.5L ambient sampling canisters, which have  plenty of sample to reach TO-15A detection limit requirements. The SK75 is also ideal for the analysis of 1-1.4L canisters, as well as 0.5-1L Bottle-Vacs. Secured by a mounting system compatible with Agilent, Thermo or Shimadzu GCMS combinations, the SK75 lives above the GCMS, taking zero bench space, to allow optimum sample throughput in even the most cramped laboratories.

The SK75 may also utilize the novel Sky Screen™ module to pre-test samples to ensure they will not contaminate a connected 7200CTS or 7200A preconcentrator, using a very fast 8-10 minutes  screening process. If approximate concentrations of canisters or Bottle-Vacs are unknown, it is far safer to screen them before preconcentrating in a trace level preconcentrator. This is easily  accomplished with the Sky Screen module, which can inject a 0.1, 0.25, or 1cc loop into the GC carrier gas for delivery to the GC or GCMS. If the GC column is maintained at 150C, most VOCs elute in  just 3-5 minutes, with zero wait time for the GC oven to get ready for the next injection. No need to risk having a bad day by accidently concentrating a high PPM level sample. The Sky Screen module  totally removes this risk, while the vacuum on the Source Level Sampling Inlet makes carryover even at the high PPM level a thing of the past.

SkyCan 40” - SK40

The SK40 is the ideal replacement for the Entech 7032XX rotary valve systems. Unlike the 7032XX that used 21 different inlet lines at potentially 21 different background levels, the SK40 uses only 1  sample inlet that is vacuum cleaned between samples to provide incredibly low carryover from run to run. Like it’s larger SK75 cousin, the SK40 can use the Sky Screen module to pre-test samples to ensure they will not contaminate the 7200CTS or 7200A preconcentrators, using a very fast 7 minute screening process. The SK40 can connect to a cryogen based 7200A, or a cryogen-free 7200CTS,  along with up to two 7016D towers to truly optimize flexibility and throughput.
