If you do not understand these 3 words, google them: symptom, symptomatic and asymptomatic. Some of us were ignorant at Clarkson but not anymore.

How many young people under the age of 18 have died while having the Corona Virus in the state of California in the USA with a population of 39.5 million?
CDPH shows 81 as of November 1, 2022. This is 0.0002% of the California population. Have a health problem or over 80, yes it is dangerous but so is the Flu and Pneumonia.
Sweden with 10 million people never had any mask mandate and had the same results as the state of California! - - References: CDPH , Flu and Sweden

SRI Gas Chromatograph Overview
From the SRI family of Gas Chromatographs, select the model which best fits your needs.
The full-featured 8610C GC can mount up to four (sometimes five or six) detectors, five injectors, and a host of accessories, yet is still small enough to ship UPS/FedEx or even check it as airline baggage for your expeditions to the field. It also fits easily on a crowded laboratory bench.
The Model 8610D GC is identical to the 8610C, except that it has dual temperature programmable column ovens.
Consider the Model 310 when you want the smallest laboratory GC available and plan to inject using a syringe. This compact chassis can mount up to four detectors and one injector.
Choose the rack-mountable Model 410 GC for 19-inch, shelf-equipped industrial racks.
The ultra-compact Model 110 can mount up to four detectors and connects to a host GC (SRI or another brand) via a heated transfer line. Pick this chassis when you need to add detectors to an existing GC, or want GC detector performance without a chromatographic separation (total hydrocarbon stream monitoring, etc.). This model does not include a PeakSimple data system as standard equipment.

Standard Features of All SRI GC Models:

Built-in, single channel PeakSimple data system (except for the Model 110).
Heavy duty, all-aluminum construction for lightweight durability.
"At-a-glance" panel display that reports the status of system heating, pressure, and voltage control zones to the bright and easy-to-read display.
Electronic Pressure Control (EPC) for all regulated gas pressures. EPC results in enhanced day-to-day reproducibility compared to mechanical pressure regulators, and allows the carrier gas pressure to be ramped from the data system.
Four, five, or six simultaneous detector capability—choose from 16 detector types.
Two year warranty and FREE technical support.
Rugged re-usable plastic container which ships UPS/FedEx and also as airline baggage. The GC is secured in the shipping container using a system of belts and buckles which eliminates the need for extra styrofoam peanuts, bubble-wrap, and other annoying packaging materials.
Since the typical GC weighs about 60lbs in the shipping container, it is easily carried by one person.

Tunable Column Selectivity GC for adjustable dual column selectivity
Rack Mount Mud-Logging GC for standard 19" racks
310 Soil Gas GC for soil & gas investigation applications
Preconfigured GC Overview

SRI Instruments specializes in CUSTOM GAS CHROMATOGRAPHS. However, they have preconfigured a number of GCs for common applications. In some cases, the preconfigured GCs are less expensive than the identical hardware assembled "a la carte." Each of the preconfigured GCs below may be further customized.

Capillary FID GC
General purpose GC
2 Narrow Bore Capillary FID GC
For semi-volatiles and high boiling compounds
3 CryoSulfur GC
For trace sulfur in gas or liquid
4 Greenhouse Gas Monitoring GC
For greenhouse gases methane, carbon dioxide and nitrous oxide
For dissolved gases in water and other liquids
For dissolved gases in transformer oil
Multiple Gas Analyzer #1 GC
For fixed gases and light hydrocarbons
Multiple Gas Analyzer #2 GC
For fixed gases, water and hydrocarbons to C20
Multiple Gas Analyzer + Sulfur GCs
For H2S, SO2, fixed gases and C1-C20 hydrocarbons
BTU Gas Analyzer GC
For BTU content of natural gas
Method 25 Methane/Nonmethane GC
For methane/nonmethane hydrocarbons as per EPA Method 25
Mud-Logging GC
For total hydrocarbons plus detailed C1-C6 content
Environmental and BTEX GCs
For most EPA series 8000 methods
TO-14 Air Monitoring GC
For EPA air monitoring methods
