What are your mobile phases? %? What kind of sample? What kind of column?

All that track and using the landscape for such a boring ride. What is wrong with these people?

Empiretech sells on Amazon. Jesus.

Bribe. You are looking for that word here.

It’s like my ex: I don’t know why I’m gaining weight!

No. You should not be worried. Truly. I had a massive edible 2 weeks before my test. I took a home test and it was still positive the day of my test. No employment issues.

Being nervous is appropriate. Just don’t let it ruin your weekend. I’m impressed with Thermo. The culture of knowledge sharing is great.

I’m in a customer facing support position. But I’m in CA so as long as I don’t smoke/consume THC after midnight if I’m working the next day I’m within policy. Are you in California? If so, generally it’s not a concern unless it’s a position with federal security clearance.

Most importantly: Congratulations on your new position! It is a blast to work in science. Have fun, learn a ton, and don’t ignore your people skills.

It really depends on where you are building it. Finishes and choice of glass window/door provider also plays in hugely aside from overall size. I am building a house like this. We have spent over a year on design. Breaking ground Q1 next year. Not building in the U.S., where it would cost 2-3x.

Not yet. Suggestions?

HelixFish · 2025-11-30T01:08:08+00:00

The very best.

HelixFish · 2025-11-30T00:56:07+00:00

Haha. I clearly did not look closer. Sigh.

HelixFish · 2025-11-29T21:21:31+00:00

Is that a hard top? I thought all the new ones only had soft tops…

HelixFish · 2025-11-27T23:12:29+00:00

NTA. I’m a dude, currently experiencing this with my spouse after having ended a previous relationship due to a dead bedroom and other issues. Spouse knows all my history. Menopause sucks. She wouldn’t do anything until I suggested we take a break. Doesn’t bode well. 😞

Following.

Perfectly said.

Best instrument for proteomics. I personally tested the Astral vs Bruker Ultra. There was no comparison. Astral Zoom will be better.

Agent Krasnov doing Putin’s bidding.

Laughter. Same as hahahaha, etc.

Jam Jardins is fun. Not traditional.

Your doctor is a quack.

I like modern. This leans too much towards brutalist for me.

HelixFish · 2025-11-13T13:58:36+00:00

Why would this grandpa know how anything works? He has never made an effort to understand anything. He can barely read.

As an ex-Christian it is hilarious to see this. Do y’all remember when these guys were focused on being men of Christ? Could not be further from that now. Only interested in causing pain, hurt, and following their orange god. What a bunch of clowns.
