I didn't mean to set sh!t off people, I'm sorry
You're fine buddy. I think some users just had a difference of opinion, possible confusion, but you are absolutely fine. Don't worry about it. You apologized 3 or 4 times in that one comment, no need to do that but very thoughtful of you to do. But it was not needed!
That's very cute, your Trump-like use of a nickname. I'm not impressed though. I'm saying I don't find it necessary for me not to trust what is on these official documents.
Tommen, I truly do not believe that user meant to give you a nickname nor to insult you in anyway. They even replied with an apology, let's get back on discussion and topic if possible. It sounds like a simple misunderstanding.
EDIT: You have now also noted this, which is great. Let's chalk it up and move on.
I had to reread my posts to see where I gave you a "nickname" . I see now your name is tommen/ not Tommy . Not sure why that offended you or why you chose to compare it to trump and get hostile but im sorry I called you Tommy
Always great to see members own up to their mistakes, apologize and move on. Good stuff. Now back on the topic at hand!
You don't believe in testing the gas on prefilled cylinders , or in general . And I do. Totally fine. Not sure why that invokes a hostile response
I do not doubt Dutch suppliers are bar none and I'm actually sure I'd trust them way more than American. I'm Trying to stress tht not everyone is from where you are .
Wouldn't mind if other experienced members lent their opinion .
I don't agree and think this is potentially dangerous to trust online prefilled cylinders without being certain of the purity .
And again , tommen I am NOT trying to cause conflict or gotchya you or anything . This is important. We have two members saying completely different things . I'm happy to be wrong . If testing the gas shouldn't be done , and we can assume all gas is pure and just test by attempting ctb without knowing for sure , I wil gladly withdraw and digress .
I think most (most is definitely not "all", though) people would agree that it's generally unwise to blindly trust online sources regarding the purity levels of tanks. While there may be exceptions based on geographic location, it's not a one-size-fits-all situation for everyone. This aligns with your point about the importance of making individual assessments—what works for one person might not be suitable for another, and that's sound advice.
If someone has access to a reputable local store, they might feel more confident in the products being sold, especially given the various legitimate industrial applications that come with specific requirements. As you noted, different countries have varying levels of oversight, and even with that oversight, purity issues can still arise.
I never said to trust suppliers all over the world. I was talking about my country.
EDIT: now this is in the conversation, it is also a very important point which is what the other poster was getting at, so it seems the two of you are now actually aligned as well.
I guess in Dutch speaking countries they can trust the suppliers.
Absolutely, I think the previous poster was highlighting the importance of not becoming overly confident just because you have reliable access to a supplier. That's fantastic for you, but not everyone reading this can share that same level of assurance, and it's wise for them to be cautious when dealing with other suppliers. If others find themselves in a similar position, your insights are certainly valuable to them, so thank you for sharing those details!
Ultimately, everyone has the right to assess their own risks and make their own decisions. It's important to remember that while something may be "potentially" dangerous (not definitively so), not everyone comes from the same background or experience. Each reader has a unique perspective, so there isn't a one-size-fits-all answer.
Personally, I believe testing for purity is crucial for such an important task. However, everyone should base their decisions on their own research, personal anecdotes, and the credibility of their sources. No one is obligated to follow any particular path, but I do think that the risk of using an impure tank—and the potential long-term consequences—makes testing worthwhile. It may involve some additional expense for an analyzer (or even just a pulse oximeter test), but it can prevent costly failures and ensure that unsuitable tanks are avoided. It's also worth noting that some suppliers still claim to offer 99.999% pure helium without updating their information, and there are instances of potentially misleading claims, particularly from certain sources (for example only, out of China). Just because something was true in the past doesn't guarantee it's still accurate today.
It does not hurt anything to be cautious and research things further. Since every location is going to differ in access, especially when purchasing online it sure seems like a good idea to work to finding ways to mitigate risks and I think the general consensus is testing, some may say an analyzer others have said even a pulse ox on finger test run, could be a good idea [

purity. I think that's where the comfort level, if it was a reputable seller comes into play (with online perhaps being a little more difficult to assess).
There's nothing wrong with extensive testing.
EDIT: you have now commented with this, which I think it bingo on the money! There is absolutely nothing wrong with testing. It can only be a positive thing to do with no downside except finding out if a tank is unreliable (which is actually then still a good thing).
Everyone can make up their own mind on whether it is necessary depending on their individual comfort levels of course.
Hope everyone finds what they are looking for and gets peace & serenity!
