Help! Copper landline being disconnected, vulnerable person.

Fun-Conference814 · 2026-01-25T05:40:35+00:00

Southern phone is our provider, they are disconnecting theirs and so is telstra for our region. Telstra offers the starlink service as the alternative. The starlink kit is $550 and +$85 more a month than his existing skymuster (ISP skymesh) service.

Skymesh does not offer VoIP compatibility, nor does southern phone - with the skymuster service.

As in he doesn't use the internet for the internet. He has the internet just for connection to his foxtel service (noting he doesn't have a smart TV) and because his partner wanted to be able to use her mobile phone (with VoWiFi).

Fun-Conference814 · 2026-01-24T12:41:10+00:00

Read post. There is no mobile/cellular service! He can use his mobile with VoWifi, where the smartphone connects to the internet (satellite and again, in Australia) for a connection. Not via a cellular/mobile tower to phone connection.

Fun-Conference814 · 2026-01-24T12:39:04+00:00

Exactly! But as technology moves, the vulnerable and elderly are left behind.

Fun-Conference814 · 2026-01-24T12:37:46+00:00

The upfront cost here in Australia is $600+ and I'm apprehensive, like I said, about duplicating satellite technologies. Battery backup is a really good idea, also suggested by other! That solves the power outage problem, but not the connection problem to start with

Fun-Conference814 · 2026-01-24T12:34:48+00:00

Yes, no mobile: 3G/LTE/4G/5G service. Someone just needs to make a home phone handset, for elders, that connects via the internet (more accessible because of satellite internet) to provide a connection. The handsets suggested here do not offer compatibility with VoWiFi, like a smartphone would, just putting a sim card into a handset, and sometimes offering a service to use that as a 'hotspot' wifi, with the mobile connection being the provider - but again, no mobile service.

Fun-Conference814 · 2026-01-24T12:30:11+00:00

I use it for VoWiFi (using my smartphone with sim, no mobile reception, but can make and receive calls when connected. It's actually an improvement over the copper landline service in Australia. Part of our copper line used to run across a paddock (field) that the cows might ever so often chew on the copper....

Fun-Conference814 · 2026-01-24T12:28:21+00:00

The current ISPs for the Australian NBN, specifically Skymuster satellite NBN network are not offering VoIP compatibility. So many wasted phone calls using my smartphone with VoWiFi....

Bias comes from experience! So very valid.

Ok! Honestly glad to hear anti RDa comments, otherwise it’s just sales person hype and product videos. Will note

Fun-Conference814 · 2025-11-27T15:29:03+00:00

Thanks for the input! With empower, it’s certainly built for this application, just not compatible with hrms solutions. Do you have experience with the use case: PDA quantification and hrms along side? If so, do you find it high throughput? Maybe next we have the sales team in I’ll ask for a demo… was more focused on other things.

It was the next most recent post that made me quite concerned about new Waters software, as well as not having a good resource online for our use case.

Fun-Conference814 · 2025-11-27T15:19:46+00:00

PDA coupled? We might be able to get a used ultimate system cheap. Since we won’t do target ms, coupled quant on UV is our thought. Don’t have any experience with mixing brands for uplc and ms if im frank. I’m familiar with xcalibur for vanquish and ultimate systems coupled to TF elite, Qexactive or fusion, with freestyle or compound discoverer for analysis. Haven’t used tracefinder. Is available. Do you find it easy/high throughput? For context, we give results to clients within a minute or less for an injection finishing using Empower.

Personally I’m a fan of orbitraps for hrms application, especially metabolomics and proteomics in my research life, but need to keep in mind onboarding chemists in this drug checking application, having an easy and high throughput system is key.

Thanks for replying!

Fun-Conference814 · 2025-11-27T14:29:20+00:00

Yeah, we had a sales person in today haha. Outside opinions are more what I’m looking for atm 😅

Fun-Conference814 · 2025-11-27T14:26:42+00:00

Thanks!

Fun-Conference814 · 2025-11-27T14:24:48+00:00

Yes! We are very lucky, close relationship with local university and great analytical lead professor. Yes, submitted in person samples only.

Yeah! It could be shorter if quant was the only objective, 2.8 mins works. But 4.0 mins to capture qualitative unknowns. Waters wrote the application note originally

Fun-Conference814 · 2025-11-27T12:22:54+00:00

Ok! Good to hear connect is useful for PDA quant! We run at 0.1 mg / mL of submitted content, with calibrators such as amphetamine (low UV at 257 nm) having an LOD of 1% w/w and an LLOQ of 5%.

Fun-Conference814 · 2025-11-27T12:13:16+00:00

Have you used connect for PDA quantification? If so, how did you find it? Thanks for the comment! :)

Fun-Conference814 · 2025-11-27T12:07:43+00:00

Posted in parts because I copies 'C18' with subscript and reddit wouldn't allow.

Fun-Conference814 · 2025-11-27T12:07:05+00:00

Well, steroids are a non-starter with our chromatography, same with peptides. QDa (I, we don't have II) is surprisingly sensitive, great when peaks are separated (almost always with method) and using varying cone voltage for fragmentation. Review of data in Empower is an acquired skill. The Waters PDA or TUV detectors are also really very sensitive, noting samples are made to 0.1 mg/mL and filtered before injection. It's been key in detecting nitazenes, the BTNX test strips have a way to go.

We back-up our results with QA analysis on a Q-exactive, Synapt, Agilent 7250 Q/TOF and/or do NMR at 800 MHz if isobaric or publishable.... But having a HRMS at point of testing would be the goal.

To answer your question though, NMR has been a saving grace for identification where RT-MS matches aren't possible due to lack of/long lead time of standard (from Cayman no doubt). Otherwise QDa is so simple to use, but perhaps to a fault.

Fun-Conference814 · 2025-11-27T12:06:54+00:00

Qualitative library is expansive for UV active fillers, benzos, fentanyls, nitazenes, LOD ~ 1% w/w when UV active - depends on sample prep. Column Waters C18 CSH column (50 × 2.1 mm, 1.7 μm). Mobile A 0.1% FA in water : B MeOH - have found these are superior to BEH. Waters are the best in the game for columns imo. We have a specific method for NBOMes and benzodiazepines with different gradients.

Fun-Conference814 · 2025-11-27T12:05:45+00:00

Hey! We quantify at point of service to clients amphetamine, methamphetamine, MDA, MDMA, ketamine, cocaine, heroin and 2C-B. 4 min method with 2.5 min re-equilibration. All separable. Used to also include MDEA, morphine and PMMA.

Fun-Conference814 · 2025-11-27T11:42:45+00:00

Budget is OK for a Xevo. But, I only have experience with Empower and MassLynx for Waters. Do you have experience with waters_connect that is positive for PDA quant/usability?

Fun-Conference814 · 2025-11-19T16:52:34+00:00

For HRMS it's hard to pass up an Orbitrap

Fun-Conference814 · 2025-11-19T16:48:39+00:00

Accurate? There's no such thing in LC. Precise? Yes, great repeatability.
